If `m,m_n` and `m_p` are masses of `._Z X^A` nucleus, neutron and proton respectively.

If m, m_(n) and m_(p) are the masses of ""_(Z)X^(A) nucleus, neutrol and proton respectively

If M, m_n and m_p are masses (in kg) of nucleus X_z^A , neutron and proton respectively, then mass defect (Deltam) is equal to

If M, m_n and m_p are masses (in kg) of nucleus X_z^A , neutron and proton respectively, then mass defect (Deltam) is equal to

M, M_(n) & M_(p) denotes the masses of a nucleous of ._(Z)X^(A) a neutron, and a proton respectively. If the nucleus is separated in to its individual protons and neutrons then

M, M_(n) & M_(p) denotes the masses of a nucleous of ._(Z)X^(A) a neutron, and a proton respectively. If the nucleus is separated in to its individual protons and neutrons then

In a fusion process a proton and neutron combine to give a deuterium nucleus. If m_(o) and m_(p) be the mass of neutron and proton respectively the mass of deuterium nucleus is

If M (A,Z), M_p and M_n denote the masses of the nucleus "_Z^AX proton and neutron respectively in units of u (lu=931.5MeV//c^2) and BE represents its bonding energy in MeV, then:

M_n and M_p represent mass of neutron and proton respectively. If an element having atomic mass M has N- neutron and Z -proton, then the correct relation will be :
