'''Sulfur''' is a relatively abundant non-metallic [[element]] (atomic number 16), also known as ''brimstone''. Surprisingly, pure sulfur is a tasteless and odorless multivalent substance, best known in [[yellow]] crystals. However, when combined with hydrogen or oxygen (as in ''hydrogen sulfide'' or ''sulfur dioxide''), we observe the "rotten [[egg]]" smell that is associated with sulfur.
Sulfur is sometimes spelled ''sulphur''. It occurs in many sulphide and sulphate minerals.
