[DOC] [TLE] Isotopes of Hydrogen - Boundless [PAR]  [DOC] [TLE] Isotopes of hydrogen - Wikipedia [PAR] The three most stable isotopes of hydrogen: protium (A = 1), deuterium (A = 2), and tritium (A = 3). Hydrogen (H) (relative atomic mass: 1.00794) has three naturally occurring isotopes, sometimes denoted 1H, 2H, and 3H. The first two of these are stable while 3H has a half-life of 12.32 years. [DOC] [TLE] Isotopes of Hydrogen - Boundless [PAR] It has a natural abundance of ~156.25 ppm in the oceans, and accounts for approximately 0.0156% of all hydrogen found on earth. The nucleus of deuterium, called a deuteron, contains one proton and one neutron (mass number = 2), whereas the far more common hydrogen isotope, protium, has no neutrons in the nucleus.
