 bis·muth /ˈbɪzməθ/ 名詞

 bismuth
 鉍

 Bis·muth n.  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° 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.
 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.
 Bismuth glance, bismuth sulphide; bismuthinite.
 Bismuth ocher, a native bismuth oxide; bismite.

 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]

 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.
