Question

Quizplus · Accepted Answer

Mass defect is the difference between the sum of the masses of individual protons and neutrons and the mass of the nucleus formed when they combine. This mass defect is converted into energy according to Einstein's famous equation, E=mc². Therefore, when a nucleus is formed from individual protons and neutrons, there is a difference in the mass before and after combination, which is the mass defect.
