Abstract
By considering nucleon and electron rest masses and with reference to nuclear charge
radius and strong coupling constant, we make an attempt to understand beta stability line and
nuclear binding energy in a simplified semi empirical approach. In this context, we consider
$\left(\frac{1}{\alpha_s}\right)\left(\frac{e^2}{8 \pi \epsilon_0 R_0}\right)\cong 4.86$ MeV as a single nuclear binding energy coefficient or potential.
