A nucleus $${}_Z^AX$$ has mass represented by M(A, Z). If M_p and M_n denote the mass of proton and neutron respectively and B.E. the binding energy in MeV, then

B.E. = [ZM_p + (A $$-$$ Z)M_n $$-$$ M(A, Z)]c²

B.E. = [ZM_p + AM_p $$-$$ M(A, Z)]c²

B.E. = M(A, Z) $$-$$ ZM_p $$-$$ (A $$-$$ Z)M_n

B.E. = [M(A, Z) $$-$$ ZM_p $$-$$ (A $$-$$ Z)M_n]c²
