Question
What is binding energy of a nucleus? Give its expression.
Advertisements
Solution
when Z protons and N neutrons combine to form a nucleus, mass equal to mass defect disappears and the corresponding energy is released. This is called the binding energy of the nucleus (BE) and is equal to (∆m) c2.
BE = (Zmp + Nmn – M ) c2
