\({m}, {m}_{{n}}\) and \({m}_{{p}}\) represents masses of \(\begin{aligned} & { }_Z^A X \end{aligned}\) nucleus, a neutron and a proton, respectively. Then:
- \({m} \lt ({A}-{Z}) {m}_{{n}}+{Z} {m}_{{p}}\)
- \(m=(A-Z) m_{n}+Z m_{p}\)
- \({m}=({A}-{Z}) {m}_{{p}}+{Z} {m}_{{n}}\)
- \(m \gt (A-Z) m_{n}+Z m_{p}\)
Answer
(A) m ( A - Z ) m _ n + Z m _ p
