A step by which an unsteady atomic nucleus dissipates its energy by radiation is radioactive decay. Radioactive decay can be alpha, beta or gamma.

The correct answer is:

Option A. elements that have a half-life.

This can be explained by:

The half-life of an element is the amount by which it gets lessened to half of its initial amount.The atoms containing the unstable and imbalanced protons and neutrons undergo radioactive decays.All the other options are incorrect and are not reasons for radioactive decay.

Therefore, an element that have a half-life is said to be radioactive.

The materials which goes radioactive decay have the following property:

A) All elements that have a half life

Explanation:

Half life is a term commonly used in Radiophysics. It can be defined as the time required for one half of the atomic nuclei of an unstable radioactive elements to decay.

For example the radioactive element Cobalt has a half life of 5.26 years, which means if we have a sample which contains 20 grams of Cobalt initially, after 5.26 years, it will reduce to 10 grams.
