Question

What is meant by mass defect of a nucleus

Answer 1

Answer:

Mass defect of a nucleus represents the mass of the energy binding the nucleus and is the difference between the mass of the nucleus and sum of the masses of the nucleon of which it is composed

Answer 2

Answer:

Summary. The mass defect of a nucleus is the difference between the total mass of a nucleus and the sum of the masses of all its constituent nucleons. The binding energy (BE) of a nucleus is equal to the amount of energy released in forming the nucleus, or the mass defect multiplied by the speed of light squared.
