WebAbstract. The first two groups of the Periodic Table have in common that their members exist principally in solution as cations, and their study is thus that of solute-solvent interactions and of ion-ion interactions. The elements Li, Be, and Mg have in addition a covalent chemistry and their covalently bonded compounds are also studied.
