Carbon Dating: All living organisms contain two isotopes (types) of carbon; carbon-12 ( 12C) and carbon-14 (14C). Carbon-12 is stable, meaning that its atoms do not decay. Carbon-14 however, is radioactive or unstable, meaning that an atom of carbon-14 may decay. It does this by throwing off an electron and thus transforming itself into Nitrogen 14. The ratio of carbon-14 to carbon-12 is the same for all living organisims, about 1/10, 000. However, once an organisim dies the carbon-14 begins...
