- Some configurations of protons and neutrons inside a nucleus are unstable. When an atomic nucleus is unstable they become stable by removing a proton or neutron through radiations. This process is called radioactive decay.
- This decay will be exponential in nature and is given by,
Here N0 is the original number of radioactive nuclei present, t is the time, and t1/2 is the half-life of the radioactive sample. This is known as the exponential law of radioactive decay.
