5 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Carbon \Car"bon\, n. (Elec.) A carbon rod or pencil used in an arc lamp; also a plate or piece of carbon used as one of the elements of a voltaic battery. From Webster's Revised Unabridged Dictionary (1913) [web1913]: Carbon \Car"bon\ (k[aum]r"b[o^]n), n. [F. carbone, fr L. carbo coal; cf Skr. [,c]r[=a] to cook.] (Chem.) An elementary substance, not metallic in its nature, which is present in all organic compounds. Atomic weight 11.97. Symbol C. it is combustible, and forms the base of lampblack and charcoal, and enters largely into mineral coals. In its pure crystallized state it constitutes the diamond, the hardest of known substances, occuring in monometric crystals like the octahedron, etc Another modification is graphite, or blacklead, and in this it is soft, and occurs in hexagonal prisms or tables. When united with oxygen it forms carbon dioxide, commonly called carbonic acid, or carbonic oxide, according to the proportions of the oxygen; when united with hydrogen, it forms various compounds called hydrocarbons. Compare {Diamond}, and {Graphite}. {Carbon compounds}, {Compounds of carbon} (Chem.), those compounds consisting largely of carbon, commonly produced by animals and plants, and hence called organic compounds, though their synthesis may be effected in many cases in the laboratory. The formation of the compounds of carbon is not dependent upon the life process. --I. Remsen {Carbon dioxide}, {Carbon monoxide}. (Chem.) See under {Carbonic}. {Carbon light} (Elec.), an extremely brilliant electric light produced by passing a galvanic current through two carbon points kept constantly with their apexes neary in contact {Carbon point} (Elec.), a small cylinder or bit of gas carbon moved forward by clockwork so that as it is burned away by the electric current, it shall constantly maintain its proper relation to the opposing point. {Carbon tissue}, paper coated with gelatine and pigment, used in the autotype process of photography. --Abney. {Gas carbon}, a compact variety of carbon obtained as an incrustation on the interior of gas retorts, and used for the manufacture of the carbon rods of pencils for the voltaic, arc, and for the plates of voltaic batteries, etc From WordNet r 1.6 [wn]: carbon n 1: an abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds [syn: {C}, {atomic number 6}] 2: a thin paper coated on one side with a dark waxy substance (often containing carbon); used to transfer characters from the original to an under sheet of paper [syn: {carbon paper}] 3: a copy made with carbon paper [syn: {carbon copy}] From U.S. Gazetteer (1990) [gazetteer]: Carbon, IA (city, FIPS 10585) Location: 41.04926 N, 94.82351 W Population (1990): 60 (36 housing units) Area: 1.8 sq km (land), 0.0 sq km (water) Carbon, IN (town, FIPS 10198) Location: 39.59893 N, 87.10750 W Population (1990): 350 (147 housing units) Area: 0.4 sq km (land), 0.0 sq km (water) Zip code(s): 47837 Carbon, TX (town, FIPS 12736) Location: 32.26858 N, 98.82671 W Population (1990): 255 (150 housing units) Area: 2.6 sq km (land), 0.0 sq km (water) Zip code(s): 76435 Carbon, WV Zip code(s): 25122 From Elements database 20001107 [elements]: carbon Symbol: C Atomic number: 6 Atomic weight: 12.01115 Carbon is a member of group 14 of the periodic table. It has three allotropic forms of it diamonds, graphite and fullerite Carbon-14 is commonly used in radioactive dating. Carbon occurs in all organic life and is the basis of organic chemistry. Carbon has the interesting chemical property of being able to bond with itself and a wide variety of other elements.
