What is the likely decay mode for a nucleus with a high neutron-to-proton ratio?.
- A.Alpha decay
- B.Beta decay
- C.Gamma decay
- D.Positron emission
Model answer
What a good answer should say
- Beta decay
Explanation
Why this works
A nucleus with a high neutron-to-proton ratio is likely to undergo beta decay to convert a neutron into a proton, thus stabilizing the ratio.
