First understand what an Isotope is:

Isotopes can be defined as the atoms of a same element or the species of an atom with different number of Neutrons but same protons (Atomic number)

Radioactive Isotopes are Isotopes that emit radiation in the form of particles or energy

They are Radioactive,because their Nuclei is unstable

3 types:
