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.

Carbon dating is used for i carbon decays slowly in a living organism to nitrogen half life years ii amount of carbon lost is continually replenished as long as the organism takes in air or food however, once the organism dies, it ceases to absorb carbon Hence, it is a good way of determining the age of certain archaeological artifacts of biological origin could be bone, fiber, wood, plant remnants etc. How carbon 14 dating is done?

How Does Carbon Dating Work
Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.
