Carbon-14 - Wikipedia
Carbon-14, C-14, C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on Februar… See more
OriginCarbon-14 is produced in the upper troposphere and the stratosphere by thermal neutrons absorbed by nitrogen atoms. When cosmic rays enter the atmosphere, they undergo various transformations, including the production of neutrons. The resulting …

The carbon-14 nucleus has six protons and eight neutrons, for an atomic mass of 14. The isotope also is used as a tracer in following the course of particular carbon atoms through chemical or biological transformations.www.britannica.com/science/carbon-14The type of carbon that we are interested in, because it is radioactive, is carbon with eight neutrons: carbon-14. It makes up about one part in a trillion of natural carbon. Since natural carbon contains all these isotopes mixed together, anything that takes up carbon from natural sources will have the same mix of isotopes in its carbon.www.khanacademy.org/science/ap-biology/natural …When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons). Carbon-14 is radioactive, with a half-life of about 5,700 years.science.howstuffworks.com/environmental/earth/ge…
