  Bismuth \Bis"muth\, n. [Ger. bismuth, wismuth: cf. F. bismuth.]
     (Chem.)
     One of the elements; a metal of a reddish white color,
     crystallizing in rhombohedrons. It is somewhat harder than
     lead, and rather brittle; masses show broad cleavage surfaces
     when broken across. It melts at 507[deg] Fahr., being easily


     fused in the flame of a candle. It is found in a native
     state, and as a constituent of some minerals. Specific
     gravity 9.8. Atomic weight 207.5. Symbol Bi.
     [1913 Webster]
  
     Note: Chemically, bismuth (with arsenic and antimony is
           intermediate between the metals and nonmetals; it is
           used in thermo-electric piles, and as an alloy with
           lead and tin in the fusible alloy or metal. Bismuth is
           the most diamagnetic substance known.
           [1913 Webster]
  
     {Bismuth glance}, bismuth sulphide; bismuthinite.
  
     {Bismuth ocher}, a native bismuth oxide; bismite.

From WordNet (r) 2.0 [wn]:

  bismuth
       n : a heavy brittle diamagnetic trivalent metallic element
           (resembles arsenic and antimony chemically); usually
           recovered as a by-product from ores of other metals [syn:
            {Bi}, {atomic number 83}]

From Elements database 20001107 [elements]:

  bismuth
  Symbol: Bi
  Atomic number: 83
  Atomic weight: 208.980
  White crystalline metal with a pink tinge, belongs to group 15. Most
  diamagnetic of all metals and has the lowest thermal conductivity of all
  the elements except mercury. Lead-free bismuth compounds are used in
  cosmetics and medical procedures. Burns in the air and produces a blue
  flame. In 1753, C.G. Junine first demonstrated that it was different from
  lead.
