Sulphur

Sulphur (or sulfur) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S₈. Elemental sulfur is a bright yellow, crystalline solid at room temperature.

Characteristics[edit | edit source]

Sulphur is characterized by its bright yellow color, its ability to form an array of compounds, and its nonmetallic properties. It is part of the Chalcogen group on the periodic table, and is highly reactive, particularly with hydrogen and oxygen.

Occurrence[edit | edit source]

Sulphur occurs naturally as the pure element (native sulphur) and as sulphide and sulphate minerals. It is an essential element for life and is found in two amino acids, cysteine and methionine.

Uses[edit | edit source]

Sulphur is used in many industries, including the manufacture of sulphuric acid, the most produced chemical in the world. It is also used in the production of fertilizers, detergents, and gunpowder.

Health Effects[edit | edit source]

While sulphur is an essential element for life, exposure to high levels can cause irritation to the eyes, nose, throat, and skin, and can cause lung damage if inhaled.
