Hydrogen Isotope

Hydrogen isotopes are different forms of the element hydrogen, which has one proton in its nucleus. The isotopes vary in the number of neutrons: ordinary hydrogen (protium) has none, deuterium has one, and tritium has two. These variations affect their mass but not their chemical behavior. Deuterium is used in scientific research and in certain industrial applications, such as tracing chemical reactions or producing heavy water for nuclear reactors. Tritium is radioactive and used in nuclear fusion research and luminous devices. Understanding isotopes helps scientists study processes in nature and develop advanced technologies.
