What are ISOTOPES??
Isotopes are atoms of the same elements but having a different number of neutrons or mass number.However, the atomic number or the number of protons stays constant and does not ever change as it is what makes the elements unique from each other.

An example of isotopes originate from carbon.
The original state of carbon atoms is actually Carbon-12. However some carbon atoms actually have some extra or less neutrons than 12.Some may have 7, some 8.Those are examples of isotopes.

Some isotopes are stable, but others are radioactive (unstable). An isotope is radioactive if its nuclei are unstable. Large atomic nuclei, with more than 83 protons and their associated complement of neutrons, are unstable. Uranium and plutonium are examples of such elements. Small atomic nuclei may also be radioactive if the ratio of neutrons to protons exceeds certain limits. Even tiny hydrogen, the smallest of atoms, has a radioactive isotope.Radioactive isotopes have certain uses, such as in agriculture application and they have medical uses as well.
