Play the game now! Radiocarbon Dating When a plant or animal dies it stops taking in carbon-14 and radioactive decay begins to decrease the amount of carbon-14 in the tissues. The age of the plant or animal specimen containing carbon, such as ldvel, bones, plant remains, is determined by measuring the ratio of carbon-12 to carbon dating a level chemistry. The half-life of carbon-14 is only 5730 years. Because of this relatively short half-life, carbon-14 can only be used to date specimens up to about 45,000 years old.

Image by Mario Modesto Mata. When researchers find a bone or artifact, how do they know how old it is? While there are a number of answers to that question, most of which depend largely on the age and surroundings of the item, carbon dating is surely one of the most important. The physics, chemistry, and biology, behind carbon dating is absolutely fascinating and worth knowing.

Scientific American Editor Michael Moyer explains the process of radiocarbon dating. What is Carbon Dating? Carbon is one of the chemical elements. Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones. All carbon atoms have a nucleus containing six protons.

Carbon-14 Dating Most everyone has heard of Carbon dating on the news or elsewhere sometime in the past years. In this article I hope to explain the theoretical and physical science behind Carbon dating, and discuss how it affects our lives and the validity of the process. Scientists use Carbon dating for telling the age of an old object, whose origin and age cannot be determined exactly by normal means. Because of this method Chemistry has become intertwined with History, Archeology, Anthropology, and Geology. Poole Many items that have been thought to come from one time have been tested and found out to actually come from a few thousands years beforehand.
