radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.
Elemental carbon exists in several forms each of which has its own physical characteristics two of its welldefined forms diamond and graphite are crystalline in structure but they differ in physical properties because the arrangements of the atoms in their structures are dissimilara third form called fullerene consists of a variety of molecules composed entirely of carbon.
carbon14 dating also called radiocarbon dating method of age determination that depends upon the decay to nitrogen of radiocarbon carbon14 carbon14 is continually formed in nature by the interaction of neutrons with nitrogen14 in the earths atmosphere the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.
carbon from latin carbo coal is a chemical element with symbol c and atomic number 6 it is nonmetallic and tetravalentmaking four electrons available to form covalent chemical bondsit belongs to group 14 of the periodic table three isotopes occur naturally 12 c and 13 c being stable while 14 c is a radionuclide decaying with a halflife of about 5730 years.
Evolutionists generally feel secure even in the face of compelling creationist arguments today because of their utter confidence in the geological time scale even if they cannot provide a naturalistic mechanism they appeal to the fact of evolution by which they mean an interpretation of earth.
carbon14 dating is a method based on unprovable assumptions about the past used to date things that contain carbon eg fossils it can only give maximum ages of around 50000 years and yet c14 has been found in fossils and diamonds thought to be millions and billions of years old respectively.
