carbon
  • 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.
  • 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.
