The following discussion focuses on Carbon 14 dating, the most widely used Willard F. Libby at the University of Chicago in the 50's, for which he received the C 14 dating provided an accurate means of dating a wide variety of organic.
The element carbon is abundant in nature, and is a basic building block of all living things. Like many elements, carbon exists in nature in several different isotopic forms. For example Carbon 12 hereafter C 12the most abundant isotope of carbon, has six protons and six neutrons in its nucleus. This transforms it to a new element of atomic number 6, which, as we know, is carbon. But this carbon isotope has the atomic weight Its two excess neutrons cause it to be very unstable, and it will eventually experience radioactive decay, changing back to the stable element nitrogen.
As C 14 circulates through the atmosphere, mostly as carbon dioxide, and is perhaps taken into the sea or transformed into plant tissue by carbon dating facilities at university of florida, it behaves just the same as C Over time, however, the number of unstable parent nuclei of C 14 decreases. That is one of the reasons that C 14 dating is useful in archaeology, whereas potassium or uranium isotopes with much longer half-lives are used to date really ancient geological events that must be measured in millions or billions of years.
Thus, dates derived from carbon samples can be carried back to about 50, years.
