Is carbon unstable

WebCarbon is a constituent (about 12% by mass) of the very large masses of carbonate rock ( limestone, dolomite, marble and so on). Coal is very rich in carbon ( anthracite contains 92–98%) [63] and is the largest commercial source of mineral carbon, accounting for 4,000 gigatonnes or 80% of fossil fuel. Carbon (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 14 of the periodic table.
