The stable isotopes of carbon
WebThe heaviest is carbon-14 (which, in the scientific world, is written as 14 C), followed by carbon-13 (13 C), and the lightest, most common carbon-12 (12 C). Different carbon reservoirs “like” different isotopes, so the relative proportion of the three isotopes is different in each reservoir - each has its own, identifying, isotopic ...
