Answer:
in the 13 th group ga is the first element before which the d block elements are present .So in the ga has completely filled 3d orbitals as inner orbitals. The d orbitals due to diffused shape provideshielding very little but the increased nulear charge creats a much more attraction on the outermost electron due to increase in the effective nuclear charge increasing the ionisation enthalpy even more than al.
