Isotope used in carbon dating - Isotope - Wikipedia


For example, carbon-12 , carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7 and 8 respectively.

The small bone sample is then treated through a set of chemical procedures, depending on the particular analysis in question. For example, for analysis of carbon and nitrogen stable isotopes, the bone is washed in hydrochloric acid (HCl) for an appropriate period of time until the bone sample is ready for the next chemistry steps. These processes are carried out to extract the "pure" bone collagen from additional components that make up bone, such as lipids and proteins.
