All atoms of a given element contain the same number of protons. Atoms of an element with different numbers of neutrons are called isotopes. The half-life is the time it takes for half of a given amount of an isotope to decay.So the organism contains less and less carbon-14 as time goes on. We can estimate the amount of carbon-14 that has decayed by measuring the amount of carbon-14 to carbon-12. With this information, we can tell how long ago the organism died. It decays quickly compared to some other unstable isotopes. Because they decay more slowly, they can be used to date much older specimens. You can learn more about these other isotopes at the link below.[Insert a link to a video about radiometric dating with isotopes other than carbon-14.] 1.

As the carbon-14 decays, it is replaced with more carbon-14. Scientists estimate the ages of rock layers in order to better understand Earth’s history and the history of life.
