WebbEqn (6) tells us to expect decreases in electronegativity when the radius of an atom is decreased under constant pressure. Electronegativity also decreases as electron–electron repulsion, quantified by the Δ Eee -term, increases. We remind that eqn (6) has been derived for compression of non-reactive atoms.
