The Frasch process uses boiling water to extract it from underground deposits.
The Claus process can produce this element from raw natural gas, and in ancient times the Sicilian process was used. The Frasch process uses boiling water to extract it from underground deposits. When rapidly cooled from a molten state, this element becomes plastic. It can form the functional group thiol with a hydrogen atom, and it forms the bonds in tertiary protein structures when formed between cysteine residues. Used in vulcanizing rubber, for 10 points, identify this element that can form a smelly gas when combined with two hydrogen ions, an element with atomic number 16 and symbol S.
