Radii, covalent Slater

Allred and Rochow chose as a measure of electronegativity of an atom the electrostatic force exerted by the effective nuclear charge eff (estimated from Slater s rules, see Box 1.6) on the valence electrons. The latter are assumed to reside at a distance from the nucleus equal to the covalent radius, r y, of the atom. Equation 1.36 gives the method of calculating values of the Allred-Rochow electronegativity, X...
