Question

What is the significance of binding energy per nucleon of a nucleus of a radioactive element?

Answer 1

The significance of binding energy is nucleon of a nucleus :

1) The binding energy per nucleon is very high then they undergo fission reaction i.s. A > 170.

2) If, it is low if undergoes fission reaction i.e. A < 30.

3) It is stable when the mass number is between 30 and 170
