Expert Answer:

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.
