Question

M_{n}

and

M_{p}

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

Options:

A . M

B . M>[NMn+ZMp]

C . M=[NMn+ZMp]

D . M=N[Mn+Mp]

Answer: Option A
:
A
Actual mass of the nucleus is always less than total mass of nucleons so

M < [N M_{n} + Z M_{p}]
