The ionisation enthalpies of group 15 elements are in the following order : ' First ionisation enthlpy < Second ionisation enthalpy < Third ionisation enthalpy '. But actually the first ionisation enthalpy should have been the highest as it involves removal of the electron from stable half filled p orbital. Please explain.
