Which statement describes what happens to elements during radioactive decay

1) They release energy.

Explanation:

The radioactive decay of chemical elements is a phenomenon in which the unstable nucleus of an atom disintegrates becoming a more stable nucleus, but due to the decay, particles such as alpha and beta particles among others are released.

A Radioactive decays releases energy (it is important to remember that energy is not created or destroyed, only transformed), in order to move from a non-stable nucleus to a more stable one.

The radioactive decay has an exponential decay, which means that it is reduced steadily over time, and this depends on the element.

The statemente that best describes what happens to elements during radioactive decay is: 1) They release energy.
