MCQ
When two light nuclei fuse to form a relatively heavier nucleus, the specific binding energy of the product nucleus is:
  • A
    Lower than that of the reacting nuclei
  • B
    Equal to that of the reacting nuclei
  • ✓
    Greater than that of the reacting nuclei
  • D
    Equal to exactly half of either of the reacting nuclei
✓

Answer

Correct option: C.
Greater than that of the reacting nuclei

The binding energy of the product nucleus will be greater than that of the reacting nuclei, because when two light nuclei fuse to form relatively heavier nucleus, energy is released. And the higher the binding energy, the more stable the nucleus is.
