Carbon-12

Carbon is an element on the periodic table that has only 2 shells. Carbon is an Isotope because there are two types of carbon, carbon 12 & carbon 14. Also carbon has the atomic number 6 and carbon 12 has the atomic mass of 12 and carbon 14 has the atomic mass of 14. Not only does this matter but carbon 12 and carbon 14 have different amounts of neutrons. But what is carbon used for well that is easy carbon is used in many steels and filters. All though it is used in steel and filters we still do not know who discovered it. Also carbon is not too dense but it still is dense enough to sink in water. Finally carbon is a nonmetal and that means that it does not conduct heat or electricity well.
