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.
How is carbon 14 produced a lot of interesting things happen in the upper atmosphere of our world much of the high energy photons of the electromagnetic spectrum is filtered out by the time light gets to the surface of the earth however in the extreme upper atmosphere there are photons striking the atmosphere of such high energy that they.
carbon dating is used to determine the age of biological artifacts up to 50000 years old this technique is widely used on recent artifacts but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.
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.
dating calculator to find the percent of carbon 14 remaining after a given number of years type in the number of years and click on calculate.
The following material has been taken from a sheet entitled several faulty assumptions are used in all radiometric dating methods carbon 14 is used for this example which was put out by dr hovind dr hovind r1 the atmospheric c14 is presently only 13 of the way to an equilibrium value.

carbon is an extraordinary element it occurs in more different forms than any other element in the periodic table the periodic table is a chart that shows how chemical elements are related to each other.
In this article an overview is presented of the status of the radiocarbon dating of ironbased materials recent advances include simplification in sample preparation and reduction in sample size for accelerator mass spectrometry measurements and the potential use of rust as a viable source of material for radiocarbon dating.
