Sulfur is the tenth most common element by mass in the universe, and the fifth most common on Earth. Though sometimes found in pure, [[native element minerals|native]] form, sulfur on Earth usually occurs as [[sulfide minerals|sulfide]] and [[sulfate minerals]]. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in [[ancient India]], [[ancient Greece]], [[history of China#Ancient China|China]], and [[ancient Egypt|Egypt]]. Historically and in literature sulfur is also called '''brimstone''',<ref name=Greenwd/> which means "burning stone".<ref>{{cite EB1911 |wstitle=Brimstone |volume=4 |page=571}}</ref> Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from [[natural gas]] and [[petroleum]]. The greatest commercial use of the element is the production of [[sulfuric acid]] for sulfate and phosphate [[fertilizer]]s, and other chemical processes. The element sulfur is used in [[match]]es, [[insecticide]]s, and [[fungicide]]s. Many sulfur compounds are odoriferous, and the smells of odorized natural gas, skunk scent, grapefruit, and garlic are due to [[organosulfur]] compounds. [[Hydrogen sulfide]] gives the characteristic odor to rotting eggs and other biological processes.
