Carbon 12 isotope used carbon dating

Radiocarbon dating—also known as carbon-14 dating—is a technique used by archaeologists and historians to determine the age of organic material.It can theoretically be used to date anything that was alive any time during the last 60,000 years or so, including charcoal from ancient fires, wood used in construction or tools, cloth, bones, seeds, and leather.Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes.When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.­ ­As soon as a living organism dies, it stops taking in new carbon.

Potassium-40 is another radioactive element naturally found in your body and has a half-life of 1.3 billion years.Carbon-12 and carbon-14 are two isotopes of the element carbon.The difference between carbon-12 and carbon-14 is the number of neutrons in each atom.The number given after the atom name (carbon) indicates the number of protons plus neutrons in an atom or ion.Atoms of both isotopes of carbon contain 6 protons. This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.
