Carbon is a non-metallic element in the second cycle of Group IVA of the periodic table. Its chemical symbol is C, its atomic number is 6, the electronic configuration [He] 2s22p2. Carbon is a very common element, which widely exists in various forms in the atmosphere and the crust. Elemental carbon to be understood very early on and use a series of carbon compounds - organic matter is essential for life. Compound carbon compounds, only the following compounds are inorganic substances: Oxides of carbon: carbon monoxide, carbon dioxide, three-carbon dioxide, nitrous oxide Carbonates, bicarbonates, Cyanide and proposed a series of proposed halogen halide intended halates: cyanide, oxygen cyanide, thiocyanate Metal carbides: for example carbonation Qiu, calcium carbide Carbon disulfide Congeners carbide: for example silicon carbide Other carbon-containing compounds are organic compounds. The carbon atom bond formed are relatively stable, the number of carbon compounds, arrangement, and type of the substituent, the location is a high degree of randomness, thus resulting in a number of very many organic phenomenon, a compound found in current human organics majority. Different organic and inorganic nature, they are generally flammable, easily soluble in water, the reaction mechanism is very complex, has now formed a separate Division of Organic Chemistry. Inorganic compound is inorganic, generally refers to elements other than carbon compounds, such as water, salt, and sulfuric acid. But some simple compounds such as carbon monoxide, carbon dioxide, carbonic acid, carbonate, cyanide, and carbide, because of their composition and properties similar to other inorganic compounds, and therefore of the inorganic compound. Most inorganic compounds can be classified as oxides, acid, alkali, salt four categories. In the synthesis of urea to manually (an organic compound) before it can be as long as the artificially synthesized compounds, which is an inorganic compound. But Friedrich Wöhler synthesis with potassium cyanate and ammonium sulfate, urea after they no longer serve as basis for distinction. Inorganic compounds referred to inorganic substances, means in addition to organic (carbon skeleton substance) was in all other elements and their compounds, such as water, such as air. Salt, sulfuric acid, carbon monoxide, carbon dioxide, carbonate, bicarbonate, cyanide, simple inorganic carbide, also belong. Most can be classified as inorganic oxides, acids, bases and salts four categories. Organisms in water, and some inorganic major inorganic ions such as Na, K, Ca2, Mg2, Cl-, SO42-, etc. See "biological elements" of. Human tissue contains almost all kinds of naturally occurring elements, in addition to carbon, hydrogen, oxygen and nitrogen mainly in the form of organic compounds, the rest collectively referred to as inorganic (mineral or ash). Therefore, inorganic mainly by: the composition of the water and inorganic salts, which can be classified as water and: bound water and free water, bound water is an important component of cell structure, free water is a good solvent, transport of substances involved in chemical reactions . Inorganic salts can be divided into: ions and compounds, ions are maintaining normal cell life activities, the compound is an intracellular composition of compounds important. Is not the same, are different.
