It is found in the gas state at room temperature, and as the source of available carbon in the carbon cycle, atmospheric CO 2 is the primary carbon source for life on Earth. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Carbon dioxide (chemical formula CO 2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. Like nickel, cobalt in the Earths crust is found only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The second element, chlor ine, becomes chlor ide, and we attach the correct numerical prefix (“tetra-”) to indicate that the molecule contains four chlorine atoms. Cobalt is a chemical element with symbol Co and atomic number 27. The name begins with the name of the first element-carbon. Eight of these oddities are Au (gold), Ag (silver), Cu (copper), FE (iron), SN (tin), Pb (lead), Sb (antimony), and Hg (mercury): All were among the elements recognized by the ancient Greeks and Romans, and the abbreviations for those are based on a Latin or Greek term for the element. Let us practice by naming the compound whose molecular formula is CCl 4. *This prefix is not used for the first element’s name. Common chemical compounds are also provided for many elements. In coordination complexes, the carbon monoxide ligand is called carbonyl. The free element, produced by reductive smelting, is a hard, lustrous, silver metal. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. History and Uses: Cobalt was discovered by Georg Brandt, a Swedish chemist, in 1739. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. Cobalt is a chemical element with the symbol Co and atomic number 27. \): Numerical Prefixes for Naming Binary Covalent Compounds Number of Atoms in Compound Element Cobalt - Co Comprehensive data on the chemical element Cobalt is provided on this page including scores of properties, element names in many languages, most known nuclides of Cobalt. Carbon monoxide ( chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air.
