Half life of carbon dating
Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.
Other resources report this half-life as the absolute amounts of 30$ years, or sometimes simply 00$ years.Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.The number of protons in the nucleus of an atom determines the element.(You can read up on radioactivity and isotopes here).Carbon-14, the radioactive version of carbon, is rare — it only makes up one trillionth of all the carbon in the world.

Chemically, carbon-14 is no different from non-radioactive carbon atoms, so it ends up in all the usual carbon places — one trillionth of the carbon atoms in air, plants, animals and us are radioactive.
