Radiocarbon dating by willard libby

The number of protons in the nucleus of an atom determines the element.For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons.“The seminar ran the whole nine years, and we began to be major contributors to the whole field.” One of the most important outcomes of its research was the discovery of carbon-14 on February 27, 1940, by two chemists, Martin Kamen and Samuel Rubin.They determined that the basic element of carbon had a radioactive isotope, carbon-14, which contained two additional neutrons and could be dated back thousands of years.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.

He tested the radioactive half-lives of numerous historic artifacts, from the bones of ancient people to the wood of a sunken ship.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.

Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.

With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.

Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.
