Sulfur S , also spelled sulphur , 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. It reacts with all metals except gold and platinum , forming sulfides ; it also forms compounds with several nonmetallic elements. Millions of tons of sulfur are produced each year, mostly for the manufacture of sulfuric acid , which is widely used in industry.

S3 CHEMISTRY NOTES SULPHUR AND ITS COMPOUNDS

In an attempt to prepare sulphur IV oxide gas, dilute sulphuric acid was reacted with barium carbonate. It is more than the number of compounds formed by all other elements. Sulfur is an essential element for growth and physiological functioning of plants. However, its content strongly varies between plant species and it ranges from 0. Sulfates taken up by the roots are the major sulfur source for growth, though it has to be reduced to sulfide before it is further metabolized. Proteins, DNA, carbohydrates, and lipids are all composed of carbon atoms bonded to each other and to atoms of other elements.

Sulphur and Its Compounds

Covalent Bond: The atomic number of carbon is 6. Its electronic configuration is 2, 4. It requires, 4 electrons to achieve the inert gas electronic configuration. But carbon cannot form an ionic bond. It could gain four electrons forming C 4- cation.

Sulfur is a chemical element that is represented with the chemical symbol "S" and the atomic number 16 on the periodic table. Because it is 0. Sulfur also takes on many forms, which include elemental sulfur, organo-sulfur compounds in oil and coal, H 2 S g in natural gas, and mineral sulfides and sulfates. This element is extracted by using the Frasch process discussed below , a method where superheated water and compressed air is used to draw liquid sulfur to the surface. Offshore sites, Texas, and Louisiana are the primary sites that yield extensive amounts of elemental sulfur.

Sulphur Cycle: Source: Sulphur and its compounds are required by plants and animals for synthesis of some amino acids and proteins. Sulphur Cycle. When sulphur dioxide enters the atmosphere it reacts with oxygen to produce sulphur trioxide or with other chemicals to make sulphur salts. The most prevalent form of sulphur entering the atmosphere is sulphur dioxide SO2. Sulphur Cycle in Atmosphere. Sulphur is one of the components that make up proteins and vitamins. The global sulfur cycle is a complex network of processes that transfer sulfur between four main reservoirs: the ocean, the ocean floor basalts, evaporite deposits and reduced marine sediments.


Allotropes: (1) Rhombic sulphur, S8 (room to 96oC); (2) Monoclinic sulphur, S.

The element sulphur has been known from the earliest times, since it is widely distributed in nature and occurs in large quantities in the uncombined form, especially in the neighborhood of volcanoes. Sicily has long been famous for its sulphur mines, and smaller deposits are found in Italy, Iceland, Mexico, and especially in Louisiana, where it is mined extensively. In combination, sulphur occurs abundantly in the form of sulphides and sulphates.

Стратмор понял, что она смертельно напугана. Он спокойно подошел к двери, выглянул на площадку лестницы и всмотрелся в темноту. Хейла нигде не было. Тогда он вернулся в кабинет и прикрыл за собой дверь, затем заблокировал ее стулом, подошел к столу и достал что-то из выдвижного ящика. В тусклом свете мониторов Сьюзан увидела, что это, и побледнела.
