Radioactive dating Carbon dating. Carbon-14 is a radioactive isotope of carbon (it has two extra neutrons in its nucleus making it unstable).

Other methods of dating are used for non-living things. 40 K decays with a half-life of 1.3 ´ 10 9 years to 40 Ar which can be trapped in rocks. A potassium-argon method of dating, developed in 1966, measures the amount of 40 Ar arising from the 40 K decay and is compared to the amount of 40 K remaining in the rock.
