Main group metal ions
WebAtoms of many main-group metals lose enough electrons to leave them with the same number of electrons as an atom of the preceding noble gas. To illustrate, an atom of an alkali metal (group 1) loses one electron and forms a cation with a 1+ charge; an alkaline earth metal (group 2) loses two electrons and forms a cation with a 2+ charge, and so on. WebFor main group metals, tetrahedral ions such as [BeF 4] 2−, [AlCl 4] −, and [Zn(NH 3) 4] 2+ are common. For the first transition series, they are quite common among anions and with very polarizable ligands, as in the blue ion [CoBr 4 ] 2− and in the blue β form (so-called for historical reasons: names used to distinguish polymorphic varieties are …
