WebCarbon (from Latin carbo 'coal') is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—its atom making four electrons available to form covalent chemical bonds. It belongs to group … WebDec 22, 2004 · Carbon is composed of three different isotopes, 14 C, 13 C and 12 C. 12 C is the most common. 13 C is about 1% of the total. 14 C accounts for only about 1 in 1 trillion carbon atoms. CO 2 produced from burning fossil fuels or burning forests has quite a different isotopic composition from CO 2 in the atmosphere.
