The number of atoms present in the carbon 14 molecule. usually carbon 14 is used to calculate the age of fossils, dinosaur bones etc.

A carbon-14 dating can be done to determine age of skeleton.Carbon 14 dating techniques were first developed by the American chemist, Willard F. Libby at the University of Chicago in the 50's, for which he received the Nobel Prize in Chemistry in 1960. It has a radio half-life (T 1/2) of 5,730 years and is a low energy beta emitter with a radioactive range in air of ten inches. It is produced currently at a fairly constant rate in the upper atmosphere through the action of cosmic radiation on Nitrogen-14. About 21 pounds of Nitrogen is converted each year making about 1/trillion atmospheric carbon atoms radioactive 14C. The 14C then makes its way fairly evenly throughout the atmosphere and living things incorporate it into their carbon “skeletons”. When they die, they no longer obtain more 14C to incorporate, and so, the 14C decays back into 14N without being replaced. A ratio can then be established and compared with the known half-life of 14C. Then an age can be obtained for the organic material.
