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.
