The Mayan calendar used 3114 BC as their reference.More recently is the radiocarbon date of 1950 AD or before present, BP.Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.It is called "Carbon-12," which is abbreviated "C." The fact that the atom has six protons is what makes it carbon.Most nitrogen atoms have seven protons and seven neutrons, so their atomic mass is 7 7 = 14.The fact that it has seven protons is what makes it nitrogen.

The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.Other atoms are also named based on the number of protons they carry.Notice in the diagram that eight different isotopes of Carbon are illustrated.Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.
