The radius$\mathrm{R}$of a nucleus of mass number$\mathrm{A}$can be estimated by the formula$\mathrm{R}=\left(1.3\times {10}^{-15}\right){\mathrm{A}}^{1/3}\mathrm{m}$. It follows that the mass density of n nucleus is of the order of:$\left(M_{prot}\cong M_{\text{neut }}\simeq 1.67\times {10}^{-27} \mathrm{kg}\right)$
