WebConsider as an example thallium (Tl) in group 13. The +1 oxidation state of Tl is the most stable, while Tl 3+ compounds are comparatively rare. The stability of the +1 oxidation state increases in the following sequence: [2] Al + < Ga + < In + < Tl +. The same trend in stability is noted in groups 14, 15 and 16. WebA comparison of ionic radii with atomic radii (Figure 8.2.7) shows that a cation, having lost an electron, is always smaller than its parent neutral atom, and an anion, having gained an electron, is always larger than the parent neutral atom.
