Is the chemical element with atomic number 16,reresented by the symbol S.It is on abundant ,multivalentnon-metal.At normal conditions sulfur atoms from cyclic octamotic molecules with chemical formula S8.Elemental sulfur is a bright yellow crystalline soli.chemically sulfur can react as either an oxidant or reducing agent.It oxidizes most metals andseveral nonmetals,including carbon,which leads to its negatives charge in most organosulfur compounds,but it reduces several strong oxidants,such as oxygen and fluorine.
