Question

Quizplus · Accepted Answer

The binding energy is the amount of energy required to completely separate the nucleons in a nucleus. The higher the binding energy, the more tightly bound the nucleons are and the more stable the nucleus is. Therefore, E is the best choice as it directly relates to the tightness of the nucleons in a nucleus.
