Question

What is Binding Energy ??

Answer 1

The energy released when a nucleus is formed because nucleons enter a more stable lower energy state. It is equal to the energy equivalent to the mass defect ( the difference between the masses of its constituents nucleons).
For most nuclei, binding energy lies between about 7 and about 9MeV per nucleon, reaching a maximum of about 9MeV for nuclei of mass number about 60.

Answer 2

ANSWER
.........

THE ENERGY WHICH IS RELEASED WHEN THE NUCLEAR IS FORMED BY THE NUCLEON MORE STABLE ENERGY.

THIS ENERGY IS EQUAL TO THE EVALUATION OF THE MASS
