Definition: Tritium is a special kind of hydrogen atom. While regular hydrogen has one proton and no neutrons, tritium has one proton and two neutrons. Because of this extra mass, tritium is heavier than regular hydrogen. Tritium is also radioactive, which means it can emit energy and particles as it breaks down over time.
Tritium is a specific, radioactive form of hydrogen with two neutrons, used mainly in scientific fields related to nuclear energy.
