I want to know that why the individual masses of proton and neutron > than mass of nucleus it means in combined form mass decreases than the individual masses due to repulsion or any other method. tell me the concept of this?

The mass of neutrons and protons forming a nucleus is greater than the mass of the nucleus. This difference is called mass defect and it is responsible for binding the nucleus together. Since mass and energy are equivalent, the decrease in mass appears in the form of binding energy which binds the nucleons together in the nucleus.

Please answer this question. Draw a graph showing the variation of binding energy per nucleon as a function of mass number A. The binding energy per nucleon for heavy nuclei (A > 170) decreases with the increase in mass number. Explain.
