[See Periodic Table of the Elements] Carbon occurs naturally as carbon-12, which makes up almost 99 percent of the carbon in the universe; carbon-13, which makes up about 1 percent; and carbon-14, which makes up a minuscule amount of overall carbon but is very important in dating organic objects.
Just the facts Carbon: From stars to life As the sixth-most abundant element in the universe, carbon forms in the belly of stars in a reaction called the triple-alpha process, according to the Swinburne Center for Astrophysics and Supercomputing.

Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.
The end result: Atoms with six protons and six neutrons — carbon.
History and Uses: Carbon, the sixth most abundant element in the universe, has been known since ancient times.
Amorphous carbon is formed when a material containing carbon is burned without enough oxygen for it to burn completely.

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.
