Sulphur or sulfur is a chemical element with symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Elemental sulphur is a bright yellow crystalline solid at room temperature. Chemically, sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases.
Though sometimes found in pure, native form, sulfur usually occurs as sulphide and sulphate minerals. Being abundant in native form, sulphur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and Egypt. In the Bible, sulphur is called brimstone. 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 sulphate and phosphate fertilizers, and other chemical processes. The element sulphur is used in matches, insecticides, and fungicides. Many sulphur compounds are odoriferous, and the smells of odorized natural gas, skunk scent, grapefruit, and garlic are due to organosulphur compounds.
Hydrogen sulfide gives the characteristic odor to rotting eggs and other biological processes. Sulphur is an essential element for all life, but almost always in the form of organosulfur compounds or metal sulfides. Three amino acids (cysteine, cystine, and methionine) and two vitamins (biotin and thiamine) are organosulfur compounds. Sulphur is one of the core chemical elements needed for biochemical functioning and is an elemental macronutrient for all organisms.
The last will and testament of Basil Valentine, monke of the order of St. Bennet: which, being alone, he hid under a table of marble, behind the high-altar of the cathedral church, in the imperial city of Erford: leaving it there to be found by him, whom Gods providence should make worthy of it: to which is added two treatises, the first declaring his manual operations, the second shewing things natural and supernatural
