What are Isotopes and Radioisotopes?
Isotopes are atoms of the same element but with different numbers of neutrons. This means they have the same number of protons but different atomic masses. Their chemical properties are mostly the same, though.
Radioisotopes, or unstable isotopes, decay on their own. They release ionizing radiation like alpha, beta, or gamma rays. This decay changes them into different elements or more stable isotopes.
The number of neutrons in radioisotopes makes them unstable. They decay to become more stable, a key process in science and industry.
