MCQ (Single Correct Answer)

-1

M_n and M_p represent the mass of neutron and proton respectively. An element having mass M has N neutrons and Z protons, then the correct relation will be

M < {N $$ \cdot $$ M_n + Z $$ \cdot $$ M_p}

M > {N $$ \cdot $$ M_n + Z $$ \cdot $$ M_p}

M = {N $$ \cdot $$ M_n + Z $$ \cdot $$ M_p}

M = N {M_n + M_p}
