A variation of an earlier formulation of electronegativity by Allen, as the average valence electron ionization energy of a ground-state atom, is proposed. It is shown that the calculated average local ionization energies on the 0.001 a.u. electronic density contours of atoms correlate very well with Allen's values. Our procedure makes it unnecessary to enumerate valence electrons, which can be a problem due to interpenetration of shells.
