If A, Z and M represents the number of nucleons, protons and mass of the nucleus respectively, then mass defect ΔM is represented by
(mp and mn are mass of a proton and a neutron respectively)
1
ΔM = [Amp + ( A - Z)mn] - M
2
ΔM = [Amp + ( A - Z)mn] - M
3
ΔM = [Zmn + ( A - Z)mn] - M
4
ΔM = [Zmp + ( A - Z)mn] - M
