An unstable nucleus undergoes gamma decay. How does the nucleus change?


AIt becomes more stable by emitting energy and particles.
BIt becomes less stable by repositioning its particles.
CIt becomes more stable by repositioning its particles.

Verified Answer :

Final answer:

During gamma decay, an unstable nucleus emits gamma radiation, which allows it to release excess energy and become more stable. Unlike other decay types that change particle composition, gamma decay primarily reduces energy. Therefore, the nucleus becomes more stable by emitting energy and not by repositioning its particles.


Explanation:

Understanding Gamma Decay

When an unstable nucleus undergoes gamma decay, it emits gamma radiation, which is a form of energy. This process does not involve the repositioning of particles in the nucleus, unlike alpha or beta decay, which involve changes in the number of protons and neutrons. Instead, gamma decay allows the nucleus to release excess energy, thereby becoming more stable.

The correct answer to how the nucleus changes during gamma decay is: It becomes more stable by emitting energy and particles. This emission reduces the energy of the nucleus without altering its overall particle composition. In contrast to other decay types, gamma decay typically occurs after other forms of decay have taken place, as the nucleus seeks to reach a lower energy state.
