Tritium
Tritium ( /ˈtrɪtiəm/ or /ˈtrɪʃiəm/; symbol T or 3H, also known as hydrogen-3) is a radioactive isotope of hydrogen. The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of protium (by far the most abundant hydrogen isotope) contains one proton... -
Deuterium
Deuterium, also called heavy hydrogen, is one of two stable isotopes of hydrogen. It has a natural abundance in Earth's oceans of about one atom in 6,420 of hydrogen (~156.25 ppm on an atom basis). Deuterium accounts for approximately 0.0156% (or on a mass basis: 0.0312%) of all naturally occurring... -

Hydrogen-5
Hydrogen (H) (Standard atomic mass: 1.00782504(7) u) has three naturally occurring isotopes, sometimes denoted H, H, and H. Other, highly unstable nuclei (H to H) have been synthesized in the laboratory but not observed in nature. The most stable radioisotope is tritium, with a half-life of 12.32... -
Hydrogen-4
Hydrogen-4 (also less commonly referred to as quadrium) is a highly unstable isotope of hydrogen. The nucleus consists of a proton and three neutrons. It has been synthesised in the laboratory by bombarding tritium with fast-moving deuterium nuclei. In this experiment, the tritium nuclei captured... -
