If A, Z and M represents the number of nucleons, protons and mass of the nucleus respectively, then mass defect Δ M is represented by ( m_p and m_n…
If $\displaystyle A, Z$ and $\displaystyle M$ represents the number of nucleons, protons and mass of the nucleus respectively, then mass defect $\displaystyle \Delta M$ is represented by
( $\displaystyle m_p$ and $\displaystyle m_n$ are mass of a proton and a neutron respectively)
Official answer
(4)
$\displaystyle \Delta M=\left[Z m_p+(A-Z) m_n\right]-M$
