${m}_{p}$ denotes the mass of a proton and  ${m}_{n}$ that of a neutron. A given nucleus of binding energy BE, contains Z protons and N neutrons. The mass m (N, Z) of the nucleus is given by 

(1) m(N, Z) = N${m}_{n}$+Z${m}_{p}$- BE${c}^{2}$

(2) m(N, Z) = N${m}_{n}$ + Z${m}_{p}$ + BE${c}^{2}$

(3) m(N, Z) = N${m}_{n}$ + Z${m}_{p}$ - BE / ${c}^{2}$

(4) m(N, Z) = N${m}_{n}$ + Z${m}_{p}$ + BE / ${c}^{2}$
