Question

Quizplus · Accepted Answer

The term for the difference between the mass of an atom and the sum of the masses of its constituent nucleons is called the mass defect. It is caused by the release of energy during the formation of the nucleus, which is in accordance with Einstein's famous equation E=mc². The energy released contributes to the binding energy that holds the nucleus together, and the mass of the nucleus is hence less than the sum of its constituent particles. This is known as the mass-energy equivalence.
