General English


  • One of the commonest elements in the universe, carbon is found in stars, meteorites and planets as well as interstellar material. It is of special interest to us because its unusual chemistry, which allows it to form very large complex molecules, is the basis of all Earthly biology.

  • noun a black material with good electrical properties of conductivity
  • noun a deposit which forms in the combustion chamber, on the piston crown and to a lesser extent in the inlet and exhaust ports, resulting from incomplete combustion especially of oil


  • A nonmetallic chemical element whose atomic number is 6. It has the highest melting point of any known element, and occurs in several allotropic forms, including diamond, graphite, charcoal, and fullerene. It is present in all known life forms on this planet, and there are more carbon compounds than those of all other chemical elements combined. It has over a dozen known isotopes, of which 2 are stable. Its applications in electronics include its use in electrodes, resistors, lamps, and microphones. Its chemical symbol is C.


  • noun one of the common non-metallic elements, an essential component of living matter and organic chemical compounds

Origin & History of “carbon”

The notion underlying carbon is probably that of ‘burning’; it has been tentatively traced back to a base *kar- ‘fire’. The word’s immediate source was French carbone, coined in the 1780s on the basis of Latin carbō ‘coal, charcoal’ (supplementing an earlier borrowing charbon ‘coal, charcoal’). It is not certain whether char and charcoal are related to it.
