Detailed information

Carbon, atomic number 6, atomic weight 12.011. Elements of Latin origin, would like to be "carbon". Carbon is nature is widely distributed in one of elements, the content of about 0.027% in the earth's crust. The form of the carbon is various, such as diamond, amorphous elemental carbon graphite; Have amorphous carbon such as coal; A complex organic compounds such as animals and plants, etc.; Carbonate as marble, etc.

Elemental carbon of physical and chemical properties depends on it crystal structure. High hardness of diamond and soft satiny graphite crystal structure is different, each have each appearance, density, melting point, etc.

Under normal temperature, the elemental carbon chemistry is stable, insoluble in water, dilute acid, dilute alkali and organic solvents; Different high temperature react with oxygen to produce co2 or carbon monoxide; In only fluorine can and halogen elemental carbon direct response; In the heating, elemental carbon more easily to be acid oxidation; Under high temperature, carbon also with many metal reaction, generating metal carbide.
