Isotopes are
distinct nuclear species (or nuclides) of the same
chemical element. They have the same
atomic number (number of
protons in
their nuclei)...

occurring isotopes,
sometimes denoted 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.
Heavier isotopes also exist...
