What is the importance of binding energy per nucleon ?
✓
Answer
Binding energy per nucleon $ = \frac{\\text{Total binding energy}}{\text{Atomic mass number}} $. It is the measure of stability of a nucleus. Greater is the binding energy per nucleon of a nucleous, much stable is the nucleus i.e. much external energy is required to decompose the nucleus into its nucleons.
