Question

modeling nuclear processes quick check
which statement best describes the effect of radioactive decay on a nucleus? (1 point)
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 can be of a different element than the original.
the resulting nucleus is more stable than the original nucleus. the nucleus must be of the same element as the original.
the resulting nucleus is less 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 is to reach a more stable state. In processes like alpha - decay or beta - decay, the element can change as the number of protons in the nucleus changes.

Answer:

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