Putting these pieces together gives the name carbon tetrachloride for this compound. Cobalt is a chemical element, lustrous silvery-gray ferromagnetic transition metal of Group 9 (VIIIB) of the periodic table with atomic number 27 and symbol Co. Several examples are found in Table 3.3.1. History and Uses: Cobalt was discovered by Georg Brandt, a Swedish chemist, in 1739. The atoms of a polyatomic ion are tightly bonded together and so the entire ion behaves as a single unit. Cobalt is used in many alloys & super alloys to make parts in aircraft engines, gas turbines, high-speed steels, corrosion-resistant alloys, and cemented carbides. The formula of the carbonate ion is CO 32. 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. The carbonate ion (see figure below) consists of one carbon atom and three oxygen atoms and carries an overall charge of 2. The name begins with the name of the first element-carbon. Element symbols for chemical elements normally consist of one or two letters from the Latin alphabet and are written with the first letter. Chemical symbols are the abbreviations used in chemistry for chemical elements, functional groups and chemical compounds. Coverage will typically include spatial location (a place name or geographic co. Let us practice by naming the compound whose molecular formula is CCl 4. The periodic table, elements being denoted by their symbols. Element Description: The extent or scope of the content of the resource. The chemical name for the chemical compound CO is carbon monoxide. *This prefix is not used for the first element’s name. \): Numerical Prefixes for Naming Binary Covalent Compounds Number of Atoms in Compound
