Sulfur 40 (organic compound)

Sulfur is a non-metallic element with the chemical symbol S and an atomic number of 16.Pure sulfur is a yellow crystal,also known as sulfur or sulfur yellow.Elemental sulfur is insoluble in water,slightly soluble in ethanol,and easily soluble in carbon disulfide CS2.Sulfur has various allotropes,including orthorhombic sulfur,monoclinic sulfur,and elastic sulfur.In sulfur crystals,sulfur atoms form cyclic eight atom molecules with the chemical formula S8.In nature,it usually exists in the form of elemental sulfur,sulfides,and sulfates,with common valence states including-2,0,+4,+6,etc.Sulfur exists in meteorites,volcanoes,hot springs,and other places,and can be used to produce sulfuric acid,sulfates,sulfites,rubber products,paper,matches,fireworks,etc.It can also be used for insecticides,bleaching and dyeing,rubber vulcanization,and the pharmaceutical industry.Sulfur is an essential element for all life,but it almost always exists in the form of organic sulfur compounds or metal sulfides.
