The original atom is referred to as the parent and the following decay products are referred to as the daughter.For example: after the it forms a component of all organic compounds and is therefore fundamental to life. Libby of the University of Chicago predicted the existence of carbon-14 before it was actually detected and formulated a hypothesis that radiocarbon might exist in living matter.The New Zealand physicist Ernest Rutherford, suggested in 1905 that the exact age of a rock could be measured by means of radioactivity.For the first time he was able to exactly measure the age of a uranium mineral.Here are some of the materials that can be successfully dated using this method: Potassium-Argon Dating Potassium-Argon (K-Ar) dating is the most widely applied technique of radiometric dating.Potassium is a component in many common minerals and can be used to determine the ages of igneous and metamorphic rocks.Shortly after Becquerel's find, Marie Curie, a French chemist, isolated another highly radioactive element, .The realisation that radioactive materials emit rays indicated a constant change of those materials from one element to another.

Herein lies the true advantage of the radiocarbon method.

They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.

Carbon-13 and carbon-14 are thus isotopes of carbon-12.

The pathway from the plant to the molecule may have been indirect or lengthy, involving multiple physical, chemical, and biological processes.

Levels of C can represent either mixtures of modern and dead carbon or carbon that was fixed from the atmosphere less than 50,000 years ago.
