Carbon-14 has a relatively short half-life of 5730 years, meaning that the amount of carbon-14 in a sample is halved over the course of 5730 years due to radioactive decay.

Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.

Understand how decay and half life work to enable radiometric dating.A hydrocarbon found in beach sediments, for example, might derive from an oil spill or from waxes produced by plants.Carbon 14 is a common form of carbon which decays exponentially over time.All carbon atoms have a nucleus containing six protons.Ninety-nine percent of these also contain six neutrons.
