The technique used is called carbon dating and in this lesson we will learn what this is and how it is used. Carbon dating, or radiocarbon dating, is a method used to date materials that once exchanged carbon dioxide with the atmosphere. In the late 1940s, an American physical chemist named Willard Libby first developed a method to measure radioactivity of carbon-14, a radioactive isotope.These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.Furthermore, if a sample has been contaminated, scientists will know about it.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.
However, once the organism dies, the amount of carbon-14 steadily decreases.
