Abstract
With reference to nuclear stability and binding energy, relationship between nuclear force and strong force is still a grey area and is a challenging task for field experts and young scientists. In this context, considering the semi empirical mass formula as a base and adapting the strong coupling constant as a bridging parameter, we make an attempt understand nuclear stability and binding energy. Points to be noted are: 1) Nuclear binding energy can be understood with one energy coefficient and three simple terms. 2) Based on the proton number, it’s stable or relatively long living mass number can be estimated directly. 3) Considering the mean stable mass number as an input, other stable and unstable nuclides binding energy can be estimated.
