Sulfur (also spelled sulphur in British English) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S 8. Elemental sulfur is a bright yellow, crystalline solid at room temperature.
14 wrz 2024 · sulfur (S), nonmetallic chemical element belonging to the oxygen group (Group 16 [VIa] of the periodic table), one of the most reactive of the elements. Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water.
Where Sulfur Is Found. Sulfur makes up only 0.05% of the Earth's crust, but it is easy to get because it occurs uncombined as the element, S 8 (eight sulfur atoms tied together into each molecule of the element and joined in a ring).
Sulfur is abundant and occurs throughout the Universe, but it is rarely found in a pure, uncombined form at Earth's surface. As an element, sulfur is an important constituent of sulfate and sulfide minerals .
Sulfur was mined near Mount Etna in Sicily and used for bleaching cloth and preserving wine, both of which involved burning it to form sulfur dioxide, and allowing this to be absorbed by wet clothes or the grape juice.
3 sie 2018 · Sulfur is found in meteorites and native in proximity to hot springs and volcanoes. It is found in many minerals, including galena, iron pyrite, sphalerite, stibnite, cinnabar, Epsom salts, gypsum, celestite, and barite. Sulfur also occurs in petroleum crude oil and natural gas.
Currently, sulfur is produced from natural gas, petroleum and fossil reserves. The largest producers of sulfur include China, Canada Japan, Chile and Indonesia. Sulfur is a vital component of all living cells and is embedded in the proteins, DNA, and large variety of enzymes of plants, animals and microbes.
