WebMay 9, 2015 · Electronegativity is a chemical property which describes how well an atom can attract an electron to itself. Values for electronegativity run from 0 to 4. Electronegativity is used to predict whether a bond between atoms will be ionic or covalent. It can also be used to predict if the resulting molecule will be polar or nonpolar. 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.
