Sulphur or sulfur (Breetish Inglis; see spellin ablo) is a chemical element wi seembol S an atomic nummer 16. It is an abundant, multivalent non-metal. Unner normal conditions, sulphur atoms furm cyclic octatomic molecules wi chemical formula S8. Elemental sulphur is a bricht yellae crystalline solid when at ruim temperatur. Chemically, sulfur can react as either an oxidant or reducin agent. It oxidizes maist metals an several nonmetals, includin carbon, which leads tae its negative charge in maist organosulfur compounds, but it reduces several strang oxidants, such as oxygen an fluorine.
