carbon in Wingdings is ♍︎♋︎❒︎♌︎□︎■︎

An elementary substance, not metallic in its nature, which ispresent in all organic compounds. Atomic weight 11.97. Symbol C. itis combustible, and forms the base of lampblack and charcoal, andenters largely into mineral coals. In its pure crystallized state itconstitutes the diamond, the hardest of known substances, occuring inmonometric crystals like the octahedron, etc. Another modification isgraphite, or blacklead, and in this it is soft, and occurs inhexagonal prisms or tables. When united with oxygen it forms carbondioxide, commonly called carbonic acid, or carbonic oxide, accordingto the proportions of the oxygen; when united with hydrogen, it formsvarious compounds called hydrocarbons. Compare Diamond, and Graphite.Carbon compounds, Compounds of carbon (Chem.), those compoundsconsisting largely of carbon, commonly produced by animals andplants, and hence called organic compounds, though their synthesismay be effected in many cases in the laboratory.The formation of the compounds of carbon is not dependent upon thelife process. I. Remsen-Carbon dioxide, Carbon monoxide. (Chem.) See under Carbonic.-- Carbon light (Elec.), an extremely brilliant electric lightproduced by passing a galvanic current through two carbon points keptconstantly with their apexes neary in contact.-- Carbon point (Elec.), a small cylinder or bit of gas carbon movedforward by clockwork so that, as it is burned away by the electriccurrent, it shall contantly maintain its proper relation to theopposing point.-- Carbon tissue, paper coated with gelatine and pigment, used inthe autotype process of photography. Abney.-- Gas carbon, a compact variety of carbon obtained as anincrustation on the interior of gas retorts, and used for themanufacture of the carbon rods of pencils for the voltaic, arc, andfor the plates of voltaic batteries, etc.
