An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in its nucleus. This results in different atomic masses for the isotopes of the same element. Isotopes can be stable or unstable, with unstable isotopes being radioactive and decaying over time. They have various applications in fields such as medicine, Archaeology, and nuclear energy.
