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
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.
From WordNet r 1.6 [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.
