The half-life of carbon-14 is approximately 5,730 years. Since the quantity represents 13% (or 13/100ths) of , it follows that This is based on the decay of rubidium isotopes to strontium isotopes, and can be used to date rocks or to relate organisms to the rocks on which they formed.

Most rocks contain uranium, allowing uranium-lead and similar methods to date them.

Other elements used for dating, such as rubidium, occur in some minerals but not others, restricting usefulness.

This is consistent with the assumption that each decay event is independent and its chance does not vary over time.

The solution is: where is the half-life of the element, is the time expired since the sample contained the initial number atoms of the nuclide, and is the remaining amount of the nuclide.
