Sulfur is usually Reduced to a state with Oxidation Number −2 and forms a S2− Ion , called a Sulfide ion, which has the electron configuration of a Noble Gas ( Argon ). In some cases sulfur is only reduced to a state with oxidation number −1. Its configuration then resembles that of Chlorine and, like it, has the tendency to form a covalent bond with another S− ion to form a disulfide (S2)2−. Oxygen can also do this; e.g. in Peroxide s such as H2O2. In many cases, each of the two sulfur atoms in a disulfide group is covalently bonded to a carbon atom in an Organic Compound , forming a Disulfide Bond , sometimes called a ''disulfide linkage'' or a ''disulfide bridge''. Such organic compounds are often biologically occurring. The tendency is a bit more elaborate in the case of sulfur, which can form Polysulfide s. SOME EXAMPLES
