Definition
Sulfur is a multivalent, nonmetallic chemical element that is abundant, tasteless, and odorless in its pure form. It naturally occurs as a bright yellow crystalline solid near volcanic regions and hot springs, but is primarily recovered today as a byproduct of petroleum and natural gas refining. Sulfur is essential for all living organisms and has a vast range of industrial, agricultural, and chemical applications.
