Then, as now, materials in this class are most commonly used as abrasives.Compounds that contain carbon and one of the more active metals are called , such as tungsten carbide (WC), form when carbon combines with a metal that has an intermediate electronegativity and a relatively large atomic radius.The Chemistry of Nonmetals The Chemistry of Hydrogen The Chemistry of Oxygen and Sulfur The Chemistry of Nitrogen and Phosphorous The Chemistry of the Halogens The Chemistry of the Rare Gases The Inorganic Chemistry of Carbon), that contain both carbon and hydrogen.The chemistry of carbon is dominated by three factors. Carbon forms unusually strong C-C single bonds, C=C double bonds, and carbon-carbon triple bonds. The electronegativity of carbon ( ions when it reacts with nonmetals.Carbon, with four valence electrons, forms covalent bonds to four neighboring carbon atoms arranged toward the corners of a tetrahedron, as shown in the figure below.Each of these -hybridized atoms is then bound to four other carbon atoms, which form bonds to four other carbon atoms, and so on.Carbon therefore forms covalent bonds with many other elements. Carbon forms strong double and triple bonds with a number of other nonmetals, including N, O, P, and S. There are two crystalline forms diamond and graphiteand a number of amorphous (noncrystalline) forms, such as charcoal, coke, and carbon black.

The chemistry of carbon dioxide dissolved in water is the basis of the soft drink industry.

They act as alloys, rather than as either salts or covalent compounds. Eventually, as our supply of natural gas is depleted, it will become economical to replace natural gas with other fuels, such as water gas, that can be produced from our abundant supply of coal.

CO and CO has a faint, pungent odor and a distinctly acidic taste.

Although gem-quality diamonds can be synthesized, the costs involved are prohibitive.

Both diamond and graphite occur as regularly packed crystals.
