Where does binding energy come from?

Solution

The energy needed to completely disintegrate a nucleus into separate protons and neutrons is known as the binding energy (BE) of a nucleus. The rest mass of a nucleus can be used to calculate its BE.
The two are related by Einstein's well-known formula equation $E = (∆ m) c^{2}$ . Here, $m = m a s s, c = s p e e d o f l i g h t a n d E = e n e r g y$
A bound system has a lower mass than its individual components; the nucleus' mass decreases with increasing nucleon interplay.
