Carbon 13 isotope dating

Carbon 12 vs Carbon 14 Carbon 12 and Carbon 14 are isotopes of Carbon. These two Carbon isotopes mainly differ in their mass number; the mass number of Carbon 12 is 12 and that of Carbon 14 is 14.Carbon 12 comes with the same number of protons and neutrons, whereas Carbon 14 has different proton and neutron numbers.In 1772 he pooled resources with other chemists to buy a diamond, which they placed in a closed glass jar.They focused the sun’s rays on the diamond with a remarkable giant magnifying glass and saw the diamond burn and disappear.

Carbon 12 is stable because it contains the same number of protons and neutrons and the Carbon 14 is unstable because there of the difference in their proton and neutron numbers. As Carbon 14 decays, it is used for the determination of archaeological samples.Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years.Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.Diamond is the hardest substance known, so its interior should be very resistant to contamination.Diamond requires very high pressure to form—pressure found naturally on earth only deep below the surface.In 1779, Swedish scientist Carl Scheele showed that graphite burned to form carbon dioxide and so must be another form of carbon.
