Molecular formula :
nature : Part IV of the Periodic System main ethnic group (group C) elements. Atomic number six. Stable isotopes : 12,13. Amu 12.0107. Allotropism with a diamond, graphite and ball recently discovered carbon (also known as fullerenes). There are non-crystalline carbon, glass-ceramics to the state, involving a very broad, such as charcoal, coal, bone char, such as coke. Density : 2.25 graphite, diamond 3.15. Graphite 3500 ° C melting point, but 3850 ° Csublimation. Valence and ± 4 +2. Thermal conductivity higher than other non-metallic. The thermal conductivity of graphite than some metals also high, and has good electrical conductivity. Diamond is the hardest natural material. Carbon is not soluble in solvents generally, but some melting of soluble metals. When the temperature is stable, with temperatures in many elements with the role. The nature and quality of single compounds exist in two forms. Both organic carbon. Carbon steel and certain high hardness and high melting point alloys important components, as well as the chemical industry, metallurgy industry, and other important raw materials. Carbon compounds, usually in addition to carbon monoxide, carbon dioxide, carbon and carbonate, other organic compounds are classified.
