This element forms cross-links in rubber vulcanization.
This element, whose most stable form is the rhombic (ROM-bick) allotrope (AL-oh-trope), is extracted by pumping superheated steam into deposits in the Frasch (FRASH) process. Thiols (THY-olls) are alcohol analogs with oxygen replaced by this element. A platinum or vanadium (vuh-NAY-dee-um) catalyst is used in the contact process, which synthesizes a compound consisting of oxygen, hydrogen, and this element. Although blue in flame test, it is yellow as a solid and a liquid. This element forms cross-links in rubber vulcanization. For 10 points, name this element with atomic number 16.
