Why the first ionization energy of group 15 elements much higher than those of corresponding group 14 elements?

The first ionization energy of group 15 elements much higher than those of corresponding group 14 elements this is due to increase in nuclear charge and extra stable configuration of the elements of this group. The extra stability of configuration is attributed to the exactly half filled p – orbitals in their valence shells.
