SSC MTS EXAM

Detailed explanation-1: -The actual mass of the atomic nucleus is always less than the mass of protons and neutrons present in the nucleus. When a nucleus is formed, energy is released. This energy is removed in the form of a reduction in total mass. This missing mass is known as the ‘mass defect’ and it accounts for the energy released.

Detailed explanation-2: -The difference between the mass of a nucleus and the sum of the masses of the nucleons of which it is composed is called the mass defect.

Detailed explanation-3: -atomic mass measurement difference is known as the mass defect and is a measure of the total binding energy (and, hence, the stability) of the nucleus.

Detailed explanation-4: -Mass defect (also called “mass deficit") is the difference between the mass of an object and the sum of the masses of its constituent particles. Discovered by Albert Einstein in 1905, it can be explained using his formula E = mc2, which describes the equivalence of energy and mass.
