    If \[m,\,{{m}_{n}}\] and \[{{m}_{p}}\] are the masses of \[_{Z}{{X}^{A}}\]nucleus, neutron and proton respectively:

    A)  \[m=\left( A-Z \right){{m}_{n}}+Z{{m}_{p}}\]

    B)  \[m<\left( A-Z \right){{m}_{n}}+Z{{m}_{p}}\]

    C)  \[m>\left( A-Z \right){{m}_{n}}+Z{{m}_{p}}\]

    D)  \[m=\left( A-Z \right){{m}_{p}}+Z{{m}_{n}}\]

    Correct Answer: B

    Solution :

    \[m<(A-Z)\,{{m}_{n}}+Zmp\] is the correct option.
