  • Isotopes of hydrogen - Wikipedia

    en.wikipedia.org/wiki/Hydrogen-7 Hydrogen (1 H) has three naturally occurring isotopes, sometimes denoted 1 H, 2 H, and 3 H. The first two of these are stable, while 3 H has a half-life of 12.32 years. There are also heavier isotopes, which are all synthetic and have a half-life less than one zeptosecond (10 −21 second). Of these, 5 H is the most stable, and 7 H is the least. Hydrogen is the only element whose isotopes have ...
