STUDIES ON ELECTRONEGATIVITY II. GROUP ELECTRONEGATIVITIES

An empirical formula based on the method for calculating the atomic electronegativity is extended to the calculation of group electronegativities, that is, x=n~*/r~* (1) where r~* is the effective radius (in A) of the central atom A in group-ABy, and n~*, the number of effective valence electrons on the atom A. For calculating x, r~* can be determined by Sanderson's method, and n~* can be…
