Why? The ionic radius of a cation is smaller than the atomic radius of the element from which it is derived. Reason: This is due to the reason that with the successive loss of electrons, the nuclear charge attracts the remaining electrons with a greater.

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.
