Sulfur is a common, nonmetallic chemical element with the symbol S and atomic number 16. Under normal conditions, its atoms form cyclic octatomic molecules with the formula S₈, resulting in a bright yellow, crystalline solid at room temperature. Sulfur is also known to be abundant and multivalent, meaning it can form multiple bonds and exhibit different oxidation states. sulphur1
