Q. Sum of first three ionization energies of $Al$ is $53.0 \,eV$ atom $^{-1}$ and the sum of first two ionization energies of $Na$ is $52.2\, eV$ atom $^{-1}$. Out of $Al$ (III) and $Na$ (II)

Classification of Elements and Periodicity in Properties

Solution:

As ionization energy is not the only criteria for the stability of an oxidation state.
