Question

an unstable nucleus undergoes gamma decay. how does the nucleus change? (1 point) it becomes more stable by repositioning its particles. it becomes less stable by emitting energy and particles. it becomes more stable by emitting energy and particles. it becomes less stable by repositioning its particles.

Explanation:

Gamma - decay is a process in which an unstable nucleus emits gamma - rays (high - energy photons) to reach a more stable state without changing the number of protons and neutrons. So, during gamma decay, the nucleus becomes more stable by emitting energy.

Answer:

It becomes more stable by emitting energy and particles.
