- B.The nucleus may undergo beta decay
- C.The nucleus will emit gamma radiation
- D.The nucleus will gain protons
Model answer
What a good answer should say
- The nucleus may undergo beta decay
Explanation
Why this works
Having too many neutrons in a nucleus causes instability, leading to the potential for beta decay. In this process, a neutron is transformed into a proton while emitting a beta particle (electron) and an antineutrino.
This transformation helps the nucleus achieve a more stable configuration by balancing the proton-to-neutron ratio, thus reducing the excess neutrons.
