MCQ
For the decay of nucleus, the possible reason which is not true
- ANeutron proton ratio too high
- BNeutron proton ratio too low
- CSize of nucleus very large
- ✓Binding energy of nucleus is more than that of its products
✓
Answer
Correct option: D.
Binding energy of nucleus is more than that of its products
d
When Binding energy of nucleus is less than that of its products then nucleus decays.
When Binding energy of nucleus is less than that of its products then nucleus decays.
