Main group metal ions
WebAn ion (/ ˈ aɪ. ɒ n,-ən /) is an atom or molecule with a net electrical charge.The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention.The net charge of an ion is not zero because its total number of electrons is unequal to its total number of … 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 …
