What is a radioactive isotope?

Answer 1

Isotopes are atoms of the same element, with the same proton number but have different numbers of neutrons hence having different nucleon numbers.

When an unstable nucleus produces radiation, such as beta, gamma, and alpha rays, it is said to be radioactive isotopes. This is the process by which the nuclei "surrender" excess energy.
