sul·fur (S),

(sŭl'fŭr),
An element, atomic no. 16, atomic wt. 32.066, that combines with oxygen to form sulfur dioxide and sulfur trioxide; these two compounds combine with water to make strong acids. Sulfur combines with many metals and nonmetallic elements to form sulfides; it is mildly laxative, and has been used to treat rheumatism, gout, bronchitis, and, externally, skin diseases.
Synonym(s): brimstone
[L. sulfur, brimstone, sulfur]
