Sulfur is a yellowish crystal-solid substance and a nonmetal. It is essential for all living things on our planet. Sulfur can be taken up from natural sources and it plays an important role for creating various amino acids. It is believed that its name has Sanskrit roots. This chemical element easily enters the reaction with oxygen and produces quite unpleasant odor. It also quickly takes soft rubbery form known as plastic sulfur. Sulfur produces a large number of chemical compounds, which include acids, oxides, sulfates, sulfites, sulfides, and others. They are extensively used in chemical industry, namely for producing fertilizers, fungicides, food preservatives, detergents, and so on. Besides, the most important uses of this chemical element include medicine, gunpowder production, producing some household goods, etc. Sulfur can be found in minerals, salts, etc., which are usually in abundance in various volcanic regions.
