The amount of energy required to remove a neutron from is
Protons attract each other via the strong nuclear force at the same time they repel each other
via the electric force. Neutrons, because they are electrically neutral, only attract other neutrons or protons via the strong nuclear force. Hence, the difference in nucleon separation energy.
