Isotopes are atoms of the same element that have different numbers of neutrons in the nucleus and therefore different atomic weights .

Isotopes may be stable or radioactive. Most elements have two or more isotopes. The isotopes most commonly used in chemistry include: carbon (12C,13C,14C), hydrogen (1H, 2H, 3H), oxygen (16O,18O), sulfur (32S, 34S) and nitrogen (14N, 15N).
