Step 1

The term radioactive decay can be defined as the process in which an unstable nucleus loses energy by the emission of radiations. They can emit alpha particles, beta particles and gamma radiations as well.

Step 2

The half-life of a given reaction can be defined as the time in which the initial concentration of the reactants reduces to half of its original value. Mathematically it can be represented as follows:
