Hydrogen (1 H) has three naturally occurring isotopes: 1 H, 2 H, and 3 H. 1 H and 2 H are stable, while 3 H has a half-life of 12.32(2) years. [3] [nb 1] Heavier isotopes also exist; all are synthetic and have a half-life of less than 1 zeptosecond (10 −21 s). [4] [5] Of these, 5 H is the least stable, while 7 H is the most.

This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.
The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium (1 H) with zero neutrons, deuterium (2 H) with one neutron, and tritium (3 H) with two neutrons. Isotopes are distinct nuclear species (or ...
Hydrogen has three naturally occurring isotopes, denoted 1 H, 2 H and 3 H. Other, highly unstable nuclei (4 H to 7 H) have been synthesized in the laboratory but not observed in nature. [40] [41] 1 H is the most common hydrogen isotope, with an abundance of >99.98%.
Fusion forces together atoms of very light, stable elements like isotopes of hydrogen, creating slightly heavier elements like helium and producing as much as four times as much energy, per unit ...
