If `m_(p)` and `m_(n)` are masses of proton and neutron respectively and `M_(1)` and `M_(2)` are masses of `._(10)MeNe^(20)` and `._(20)Ca^(40)` nucleus repectively, then:

m_(p) and m_(n) are masses of proton and neutron respectively. An element of mass M has Z protons and N neutrons then

m_(P) and m_(n) are masses of proton and neutron respectively. An element of mass m has Z protons and N neutrons, then

m_(P) and m_(n) are masses of proton and neutron respectively. An element of mass m has Z protons and N neutrons, then

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 masses of ._Z X^A nucleus, neutron and proton respectively.

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