As Triton (from ancient Greek τρίτον , Tríton = "the third"), the nucleus , that is the cation , the "super-heavy" hydrogen - isotope tritium 3 denotes H. Its symbol is t or also 3 H + . A triton consists of two neutrons and one proton .
The Triton is unstable and, with a half-life of 12.32 years, decomposes into a helion through beta decay .
Tritons play a role in nuclear fusion reactions in future fusion reactors .
The atomic nuclei of the two other hydrogen isotopes 1 H ( protium ) and 2 H ( deuterium ) are known as protons and deuterons . The collective name for the cations of hydrogen regardless of their nuclear mass is hydron .
