Question

which statement describes radioactive decay? (1 point)
an stable nucleus gives off particles or energy to become less stable.
a stable nucleus takes in particles or energy to become less stable.
an unstable nucleus takes in particles or energy to become more stable.
an unstable nucleus gives off particles or energy to become more stable.

Explanation:

Radioactive decay occurs when an unstable nucleus emits particles or energy (such as alpha, beta, or gamma radiation) to transform into a more stable nucleus. Stable nuclei do not undergo radioactive decay as they are already in a stable state. The process is about an unstable nucleus losing (giving off) something (particles or energy) to reach a more stable configuration, not taking in particles or energy.

Answer:

An unstable nucleus gives off particles or energy to become more stable.
