An isotope of a Carbon atom containing 6 protons and 8 neutrons. Its radioactive decay over time is very predictable, and therefor is used to date how old something containing carbon is.

Carbon-14 is a naturally occuring radioactive isotope of carbon, with a half life of about 5700 years. Living creatures continually consume and produce C-14, but stop once they expire. Given the known half-life (C-14 emits beta particles to form N-14), a measure of the C-14 remaining vs. the amount known to be in nature can be used to determine the age of formerly living things, up to about 50,000 years ago (10 half-lives, at which point the remaining radioactivity can usually not be distinguished from background radiation).

Carbon-14, 14C, or radiocarbon, is a radioactive isotope of carbon discovered on February 27, 1940, by Martin Kamen and Sam Ruben. Its nucleus contains 6 protons and 8 neutrons. Its presence in organic materials is used extensively as basis of the radiocarbon dating method to date archaeological, geological, and hydrogeological samples.

Radio carbon method is the method estimating the age of old objects containing organic substancesaccording to the measurement of the decay of a particular type of carbon,C-14,in theses objects.

Carbon 14 is an isotope of normal carbon, it is formed by cosmic ray radiation. It it used as a means of dating objects, as it has a very long half life.

that's a type of carbon which is used to determine the age of things.
