Radiocarbon Dating One method that scientists use to date ancient fossils and artifacts is called radiocarbon dating.

All living things on Earth are made up of a high percentage of an element called carbon.

They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.

Carbon-13 and carbon-14 are thus isotopes of carbon-12.

Signals of this kind are often used by chemists studying natural environments.

A hydrocarbon found in beach sediments, for example, might derive from an oil spill or from waxes produced by plants.As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.Carbon-14 is most abundant in atmospheric carbon dioxide because it is constantly being produced by collisions between nitrogen atoms and cosmic rays at the upper limits of the atmosphere.The thesaurus of synonyms and related words is fully integrated into the dictionary.Click on the thesaurus category heading under the button in an entry to see the synonyms and related words for that Blog A must for anyone with an interest in the changing face of language.Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.
