Radioactive decay occurs when an unstable nucleus loses energy

So the answer is the second choice

Answer 2

All of the above

Step-by-step explanation:

Hello,

In this case, since radioactive decay is the spontaneous breakdown of an atomic nucleus resulting in the release of energy and matter from the nucleus, we confirm that it is a spontaneous process as no initiator is required; therefore, no requirement of energy is done and it occurs when an unstable nucleus loses energy.

Best regards.
