- Radioactive decay is the process by which unstable nuclei spontaneously lose energy to become stable. This process will alter the Z and N value till the element becomes stable.
- The rate at which this decay takes place in a given sample of radioactive material is called activity.
- It is given by,
Here N is the number of radioactive nuclei and λ is the decay constant.
