Question

which statement best describes the effect of radioactive decay on a nucleus? (1 point)
the resulting nucleus is less stable than the original nucleus. the nucleus can be of a different element than the original.
the resulting nucleus is more stable than the original nucleus. the nucleus can be of a different element than the original.
the resulting nucleus is less stable than the original nucleus. the nucleus must be of the same element as the original.
the resulting nucleus is more stable than the original nucleus. the nucleus must be of the same element as the original.

Explanation:

Radioactive decay occurs when an unstable nucleus loses energy by emitting radiation. The goal of radioactive decay is to reach a more stable state. During processes like alpha - decay or beta - decay, the number of protons in the nucleus can change, which can result in a different element.

Answer:

The resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.
