Atomic Number of Yttrium. Singular. [42], Yttrium has no known biological role, though it is found in most, if not all, organisms and tends to concentrate in the liver, kidney, spleen, lungs, and bones of humans. Yttrium also finds use in fuel cells for powering cars and buses, computers and digital phones and, potentially, buildings. [50][51], Rare-earth elements (REEs) come mainly from four sources:[52]. Chemistry in its element is brought to you by the Royal Society of Chemistry and produced by. The s-process is a slow neutron capture of lighter elements inside pulsating red giant stars. There are three electrons outside of the noble gas core. For more information on the Visual Elements image see the Uses and properties section below. It was called an’ earth’ because it was yttrium oxide, Y. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Apart from this, there are lots of everyday applications for yttrium compounds In its compounds yttrium is always present as the yttrium three plus ion, which means that it is colourless and has no unpaired electrons; therefore it does not have any interesting magnetic or spectroscopic properties of its own. Now, whilst no reputable scientist would argue that a magnetic monopole could open an inter-dimensional portal, its existence isn't outside the realms of possibility and if recent reports are anything to go by, it could depend on an otherwise mundane metallic element that you can find skulking around near the bottom of the Periodic Table - holmium. By reacting the resulting yttrium oxide with hydrogen fluoride, yttrium fluoride is obtained. A measure of how difficult it is to compress a substance.
Yttrium Element: Yttrium is a chemical element and it is a member of group 3 and period 5 in the periodic table.

Appearance Yttrium is a silvery-white, soft metal which is relatively stable in air due to formation of the oxide film. It is also used to make superconductors. Elements are organised into blocks by the orbital type in which the outer electrons are found. The ground state electronic configuration of neutral yttrium is [Kr].4d 1.5s 2 and the term symbol of yttrium is 2 D 3/2.. Yttrium: description Your user agent does not support the HTML5 Audio element. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). At least 32 synthetic isotopes of yttrium have been observed, and these range in atomic mass number from 76 to 108. Covalent radiusHalf of the distance between two atoms within a single covalent bond. [6] Electron spin resonance studies indicated the formation of Y3+ and (C82)3− ion pairs. Radioembolization is a low toxicity, targeted liver cancer therapy that uses millions of tiny beads made of glass or resin containing radioactive yttrium-90. [69][70][71], YAG, yttria, yttrium lithium fluoride (LiYF4), and yttrium orthovanadate (YVO4) are used in combination with dopants such as neodymium, erbium, ytterbium in near-infrared lasers. [27] While most of yttrium's isomers are expected to be less stable than their ground state, 78mY, 84mY, 85mY, 96mY, 98m1Y, 100mY, and 102mY have longer half-lives than their ground states, as these isomers decay by beta decay rather than isomeric transition. [82] Major manufacturer of LFP batteries is Shenzhen Smart Lion Power Battery Limited, with brands Winston and Thunder Sky.[83]. Elements are organised into blocks by the orbital type in which the outer electrons are found. [6] Yttrium is so close in size to the so-called 'yttrium group' of heavy lanthanide ions that in solution, it behaves as if it were one of them. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3. [11][16] Even though the lanthanides are one row farther down the periodic table than yttrium, the similarity in atomic radius may be attributed to the lanthanide contraction. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. The up side of this is that yttrium compounds make very good host materials for other lanthanides. Each shell can contain only a fixed number of electrons: The first shell can hold up to two … (ii) All the elements in a period have different valence shell electronic configuration because they have different number of electrons in the valence shell. High = substitution not possible or very difficult. [62], Yttrium can be used to deoxidize vanadium and other non-ferrous metals. [32] In the decades after Antoine Lavoisier developed the first modern definition of chemical elements, it was believed that earths could be reduced to their elements, meaning that the discovery of a new earth was equivalent to the discovery of the element within, which in this case would have been yttrium. Yttrium's stable isotope is 89Y, which has 89 - 39 = 50 neutrons. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. If you wish to use the Images in a manner not permitted by these terms and conditions please contact the Publishing Services Department by email. Common chemical compounds are also provided for many elements. [64] Yttrium is used in gas mantles for propane lanterns as a replacement for thorium, which is radioactive. The red component of color television cathode ray tubes is typically emitted from a yttria (Y2O3) or yttrium oxide sulfide (Y2O2S) host lattice doped with europium (III) cation (Eu3+) phosphors. Yttrium, complete electron configuration. He reported that the miner… 1 2 3 The number of protons and neutrons is the same. Text © The Royal Society of Chemistry 1999-2011
[46], The radioactive isotope yttrium-90 is used in drugs such as Yttrium Y 90-DOTA-tyr3-octreotide and Yttrium Y 90 ibritumomab tiuxetan for the treatment of various cancers, including lymphoma, leukemia, liver, ovarian, colorectal, pancreatic and bone cancers. [6] Yttrium is also used in the production of electrodes, electrolytes, electronic filters, lasers, superconductors, various medical applications, and tracing various materials to enhance their properties. [27] Yttrium isotopes with mass numbers at or above 90 decay primarily by electron emission (neutron → proton) to form zirconium (Z = 40) isotopes. What is known is that the composition of the copper-oxide materials must be precisely controlled for superconductivity to occur. The arrangements of electrons above the last (closed shell) noble gas. In such cases we would ask you to sign a Visual Elements licence agreement, tailored to the specific use you propose. An n − t y p e semiconductor is formed by doping pure germanium or silicon crystal with suitable impurity atoms of valency five. Then in 1986 two scientists working at IBM in Zurich, Georg Bednorz and Karl Müller, found that lanthanum barium copper oxide became superconducting at what was then almost a record high temperature, 35 degrees above absolute zero. Yttrium is concentrated in the HREE group because of its ion size, though it has a lower atomic mass. Yttrium currently has no known biological role, and it can be highly toxic to humans, animals and plants. [12] 89Y has a mass number close to 90 and has 50 neutrons in its nucleus. Yttrium Y Element 39 Mass Number: 89 Atomic weight: 88.905 g/mol Atomic number (Z): 39 Electrons: 39 Protons: 39 Neutrons: 50 Period: 5 Group: 3 Block: d 5s2 and the term symbol is 2D3/2. Yttrium oxide is added to the glass used to make camera lenses to make them heat and shock resistant. "This REY-rich mud has great potential as a rare-earth metal resource because of the enormous amount available and its advantageous mineralogical features," the study reads. In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. [48] In experiments on animals, yttrium and its compounds caused lung and liver damage, though toxicity varies with different yttrium compounds. Yttrium is often used as an additive in alloys. Yttrium atoms have 39 electrons and the shell structure is 2.8.18.9.2. 89Y is the only stable isotope, and the only isotope found in the Earth's crust. The oxidation state of an atom is a measure of the degree of oxidation of an atom. However there is a lot of funny facts about Yttrium that most people don't know. [79], A neodymium-doped yttrium-aluminium-garnet laser has been used in an experimental, robot-assisted radical prostatectomy in canines in an attempt to reduce collateral nerve and tissue damage,[80] and erbium-doped lasers are coming into use for cosmetic skin resurfacing.[6]. 150–152. Specific heat capacity is the amount of energy needed to change the temperature of a kilogram of a substance by 1 K. A measure of the stiffness of a substance. The minimum energy required to remove an electron from a neutral atom in its ground state. Political stability of top reserve holder. A percentile rank for the political stability of the top producing country, derived from World Bank governance indicators. And so the Oscar for best supporting role goes to, you guessed it, Yttrium. The energy released when an electron is added to the neutral atom and a negative ion is formed. [63], Yttrium compounds are used as a catalyst for ethylene polymerization. The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element. Murray Robertson is the artist behind the images which make up Visual Elements. [47] Normally, as little as 0.5 milligrams is found in the entire human body; human breast milk contains 4 ppm. This is approximately the sum of the number of protons and neutrons in the nucleus. Yttrium's atomic number is 39. Yttrium has no known biological role. [42] In the following decades, seven other new metals were discovered in "Gadolin's yttria". [12] Yttrium nitride (YN) is formed when the metal is heated to 1000 °C in nitrogen. 4d1.
A horizontal row in the periodic table. Yttrium is a chemical element with atomic number 39 which means there are 39 protons and 39 electrons in the atomic structure. The value of ml determines the number of orbitals in a subshell. Yttrium is a silvery white, moderately soft, ductile metal. Atomic Number of Yttrium Atomic Number of Yttrium is 39. Members of a group typically have similar properties and electron configurations in their outer shell. Concept: Formation and Properties of Ionic Compounds [22]) Some trimerization reactions were generated with organoyttrium compounds as catalysts. The temperature at which the solid–liquid phase change occurs. An integrated supply risk index from 1 (very low risk) to 10 (very high risk). The atomic number of yttrium is 39 and it is indicated by symbol is Y. As the impurity atoms take the position of G e atom in germanium crystal, its four electrons form covalent bonds by sharing electrons with the neighbouring four atoms of germanium whereas the fifth electron is left free. Ytterbium is a chemical element with the symbol Yb and atomic number 70. The RSC maintains this Site for your information, education, communication, and personal entertainment. [11], Water readily reacts with yttrium and its compounds to form Y2O3. [11] When finely divided, however, yttrium is very unstable in air; shavings or turnings of the metal can ignite in air at temperatures exceeding 400 °C. When the counter-ion is nitrate, the light lanthanides are removed, and when the counter-ion is thiocyanate, the heavy lanthanides are removed. As expected by periodic trends, it is less electronegative than its predecessor in the group, scandium, and less electronegative than the next member of period 5, zirconium; additionally, it is more electronegative than lanthanum, but less electronegative than lutetium due to the lanthanide contraction.
D Y is in the same period of the Periodic Table as X 28 Na,Which statements about a sodium atom, 23 11 are correct? It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3. [7], There is disagreement in the literature whether lanthanum (La) or, Metastable isomers have higher-than-normal energy states than the corresponding non-excited nucleus and these states last until a. Earths were given an -a ending and new elements are normally given an -ium ending. There are many possible applications for YBCO; for example MRI scanners could be made to operate more cheaply at a higher temperature using liquid nitrogen coolant. Atomic number It’s Elemental - The Periodic Table of Elements. Hence, the elements in a period have different chemical properties. The number of atoms of the element per 1 million atoms of the Earth’s crust. [11], The similarities of yttrium to the lanthanides are so strong that the element has historically been grouped with them as a rare-earth element,[5] and is always found in nature together with them in rare-earth minerals. But LYP, offer higher cathode stability, and prolong life of battery, by protecting physical structure of the cathode, especially at higher temperatures and higher charging / discharge current. Density: 4.47 grams per cubic centimeter 7. [8][9][10] Yttrium is the first d-block element in the fifth period. Values are given for typical oxidation number and coordination. The oxalate is converted into the oxide by heating under oxygen. 12–13). This Site has been carefully prepared for your visit, and we ask you to honour and agree to the following terms and conditions when using this Site. Data for this section been provided by the British Geological Survey. Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. These values were determined using several different methods. In addition technical terms are linked to their definitions and the menu contains links to related articles that are a great aid in one's studies. The leading countries for these reserves included Australia, Brazil, China, India, and the United States. It increases the strength of aluminium and magnesium alloys. He called it a magnetic monopole substance - one that instead of having poles, plural, like an ordinary magnet, had a pole. [11], As a trivalent transition metal, yttrium forms various inorganic compounds, generally in the oxidation state of +3, by giving up all three of its valence electrons. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. State at room temperature: Solid [7] The Occupational Safety and Health Administration (OSHA) limits exposure to yttrium in the workplace to 1 mg/m3 over an 8-hour workday. The name is historical and comes from the village of Ytterby, in Sweden where, in 1787, the chemist Arrhenius found a new mineral and named it ytterbite. In rats, inhalation of yttrium citrate caused pulmonary edema and dyspnea, while inhalation of yttrium chloride caused liver edema, pleural effusions, and pulmonary hyperemia. The temperature at which the solid–liquid phase change occurs.

The Kossel shell structure of yttrium. The radioactive microspheres are delivered directly to the blood vessels feeding specific liver tumors/segments or lobes. The number of electrons in each of yttrium's shells is 2, 8, 18, 9, 2 and its electron configuration is [Kr] 4d 1 5s 2.The yttrium atom has a radius of 177.6.pm and its Van der Waals radius is 200.pm. [17], One of the few notable differences between the chemistry of yttrium and that of the lanthanides is that yttrium is almost exclusively trivalent, whereas about half the lanthanides can have valences other than three; nevertheless, only for four of the fifteen lanthanides are these other valences important in aqueous solution (CeIV, SmII, EuII, and YbII). [27] The least stable of these is 106Y with a half-life of >150 ns (76Y has a half-life of >200 ns) and the most stable is 88Y with a half-life of 106.626 days. Smith's 117, however, was a strange material that could be used to open a window to another dimension. The RSC makes no representations whatsoever about the suitability of the information contained in the documents and related graphics published on this Site for any purpose. [7] Workers exposed to airborne yttrium europium vanadate dust experienced mild eye, skin, and upper respiratory tract irritation—though this may be caused by the vanadium content rather than the yttrium. Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. YSZ is also used to make the lambda sensors fitted to the exhaust sytem of your car. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain.
That has the unusual property of conducting oxide ions, making it very useful in these fuel cells. Some elements exist in several different structural forms, called allotropes. Y. Commercial use of the Images will be charged at a rate based on the particular use, prices on application.
The higher the associated electronegativity number, the more an element or compound attracts electrons … Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. The atomic number of each element increases by one, reading from left to right. Group
The description of the element in its natural form. [68] Yttrium aluminium garnet (Y3Al5O12 or YAG) has a hardness of 8.5 and is also used as a gemstone in jewelry (simulated diamond). [56] The single crystals of doped YAG are normally produced by the Czochralski process. [46] Lunar rock samples collected during the American Apollo Project have a relatively high content of yttrium. Prompting other scientists to dust off their Periodic Tables, and try switching the lanthanum portion for other similar metals. Images © Murray Robertson 1999-2011

Where more than one isotope exists, the value given is the abundance weighted average. Johan Gadolin, named by Anders Gustaf Ekeberg. [13] Concentrated nitric and hydrofluoric acids do not rapidly attack yttrium, but other strong acids do. It is a silver metallic transition metal that has properties similar to lanthanoids and is a rare earth mineral. The percentage of a commodity which is recycled. Yttrium is a silvery white, moderately soft, ductile metal. A small amount of yttrium oxide is added to zirconium oxide to make what is known as yttria-stabilized zirconia (also called YSZ). Similar to LFP, LYP batteries offer high energy density, good safety and long life. So, that is yttrium for you.

[44] Since liquid nitrogen is less expensive than the liquid helium required for metallic superconductors, the operating costs for applications would be less. The story of yttrium’s discovery begins in 1787, when Carl Arrhenius found a coal-like mineral in a feldspar/quartz mine near Ytterby, Sweden. In the case of Yttrium the group number is 3. [27] Though 90Y has a short half-life, it exists in secular equilibrium with its long-lived parent isotope, strontium-90 (90Sr) with a half-life of 29 years.[12]. Elements are shown from atomic number 1 (hydrogen) up to 94 (plutonium). Some elements exist in several different structural forms, called allotropes. If you are in any doubt, please ask. The temperature of an arc furnace of greater than 1,600 °C is sufficient to melt the yttrium.[46][60]. [29] Thinking it was an unknown mineral containing the newly discovered element tungsten,[30] he named it ytterbite[e] and sent samples to various chemists for analysis.
Atomic symbol (on Periodic Table of Elements): Y 3. The metal readily reacts with diluted [26], Yttrium isotopes are among the most common products of the nuclear fission of uranium in nuclear explosions and nuclear reactors. Colourless, unspectacular, but undoubtedly fulfilling a lot of important supporting roles. Chemical symbol for Yttrium is Y. Investigators are looking into depositing YBCO on top of flexible metal wires, and research into this continues. "Element 39: Yttrium". It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system. This may not seem much of a temperature difference, but it meant that YBCO could be kept in the superconducting state using liquid nitrogen, rather than the much more expensive liquid helium. Allotropes
[11], With halogens, yttrium forms trihalides such as yttrium(III) fluoride (YF3), yttrium(III) chloride (YCl3), and yttrium(III) bromide (YBr3) at temperatures above roughly 200 °C. The temperature at which the liquid–gas phase change occurs. The element also used to provide the red colour for early colour television screens, and this is the reason for the background which echoes the Warner Bros. ‘That’s all Folks!’ cartoon splash screen. The following rules are followed for writing the number of electrons in different energy levels or shells: The maximum number of an electrons present in a shell is given by formula 2n 2, where ‘n’ is the orbit number or energy level index 1,2,3 … Hence, the maximum number of electrons in different shells are as: In first orbit or K-shell (n=1) = 2 * N 2 = 2 * 1 2 = 2. [27][d] Multiple excitation states have been observed for 80Y and 97Y. Chemical Properties of Yttrium. Also see radioembolization in the case of combined cirrhosis and hepatocellular carcinoma. Uses Combined with europium to make red phosphors for color TV's. [44] This superconductor is notable because the operating superconductivity temperature is above liquid nitrogen's boiling point (77.1 K). [29], Until the early 1920s, the chemical symbol Yt was used for the element, after which Y came into common use. Our yttrium page has over 200 facts that span 92 different quantities. [g][33][34][35], Friedrich Wöhler is credited with first isolating the metal in 1828 by reacting a volatile chloride that he believed to be yttrium chloride with potassium. Medium = substitution is possible but there may be an economic and/or performance impact
Yttrium aluminium garnet, also known as YAG, is a very important synthetic mineral. 39 protons and 39 electrons. However, the lanthanide rare earths contain elements of even atomic number and many stable isotopes. B The nearest noble gas to yttrium is krypton, so yttrium is predicted to lose three electrons to form Y 3+, which has the same number of electrons as krypton. Or add 1 % of neodymium to YAG and you get the most widely used solid-state laser material. Atomic Mass 88,90585 Learn more about the atomic mass. Bednorz and Müller won the Nobel Prize for Physics in 1987 for this discovery. [12] As a metal, yttrium is used on the electrodes of some high-performance spark plugs. Yttrium metal of 99.9% purity is commercially available at a cost of about $75/oz. A percentile rank for the political stability of the country with the largest reserves, derived from World Bank governance indicators. This is approximately the sum of the number of protons and neutrons in the nucleus. [12][6][i] The red color itself is emitted from the europium while the yttrium collects energy from the electron gun and passes it to the phosphor. Atomic mass: 88.906 4. High = substitution not possible or very difficult. In the context of nuclear waste management, the most important isotopes of yttrium are 91Y and 90Y, with half-lives of 58.51 days and 64 hours, respectively. Yttrium oxysulfide used to be widely used to produce red phosphors for old-style colour television tubes. The sum of the oxidation states within a compound or ion must equal the overall charge.
