Watch Physics > Nuclei Videos

If m, ${\mathrm{m}}_{\mathrm{n}}$ and ${\mathrm{m}}_{\mathrm{p}}$ are the masses of ${}_{\mathrm{Z}}\mathrm{X}^{\mathrm{A}}$ nucleus, neutron and proton respectively
(a) $\mathrm{m}<\left(\mathrm{A}-\mathrm{Z}\right){\mathrm{m}}_{\mathrm{n}}+{\mathrm{Zm}}_{\mathrm{p}}$        (b) $\mathrm{m}=\left(\mathrm{A}-\mathrm{Z}\right){\mathrm{m}}_{\mathrm{n}}+{\mathrm{Zm}}_{\mathrm{p}}$
(c) $\mathrm{m}=\left(\mathrm{A}-\mathrm{Z}\right){\mathrm{m}}_{p}+{\mathrm{Zm}}_{\mathrm{n}}$        (d) $\mathrm{m}>\left(\mathrm{A}-\mathrm{Z}\right){\mathrm{m}}_{\mathrm{n}}+{\mathrm{Zm}}_{\mathrm{p}}$

(a) The mass of nucleus formed is always less than the sum of the masses of the constituent protons and neutrons i.e. $\mathrm{m}<\left(\mathrm{A}-\mathrm{Z}\right){\mathrm{m}}_{\mathrm{n}}+{\mathrm{Zm}}_{\mathrm{p}}$.
