Radioactive decay happens to some chemical elements. Most chemical elements are stable. Stable elements are made up of atoms that stay the same. Even in a chemical reaction , the atoms themselves do not change ever. In the 19th century, Henri Becquerel discovered that some chemical elements have atoms that change over time. In , Marie and Pierre Curie called this phenomenon radioactive decay.

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon. At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.
