- 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. The half-life for a radioactive element is the time it would take for the activity to reach half its original value.
- Half-life is given by,
Here λ is the decay constant, the decay probability per nucleus per second.
