While metals of the p, d and f block of the periodic table have all been shown to engage in π systems, there has never before been any aromatic or antiaromatic compounds containing s-block elements. Later, it was discovered that the elements being classified as alkaline earth metals were actually oxides of those metals — the metal atoms were combining with oxygen. The alkaline earth metals are the second group of metals on the periodic table.They are related to the Alkali metals, but they do not react as much because they need more energy to remove their two electrons, So they do not have to be stored in petrol.As ions they have a charge of +2a. The structure of Na 3 As is complex with unusually short Na–Na distances of 328–330 pm which are shorter than in sodium metal, and this indicates that even with these electropositive metals the bonding cannot be straightforwardly ionic.
