the amount of energy required to break a nucleus into individual protons and neutrons is called\nmass - energy equivalence\nmass defect\nbinding energy\nmass - energy conservation
Answer
Brief Explanations:
Mass - energy equivalence relates mass and energy by $E = mc^{2}$. Mass defect is the difference between the sum of the masses of individual nucleons and the mass of the nucleus. Binding energy is the energy required to break a nucleus into individual protons and neutrons. Mass - energy conservation is a general principle.
Answer:
C. binding energy
