Princeton's WordNet

  1. bismuth, Bi, atomic number 83noun

    a heavy brittle diamagnetic trivalent metallic element (resembles arsenic and antimony chemically); usually recovered as a by-product from ores of other metals


  1. bismuthnoun

    a chemical element (symbol Bi) with an atomic number of 83.

  2. Etymology: Uncertain; perhaps weiß Masse.

Samuel Johnson's Dictionary

  1. Bismuthnoun

    The same as marcasite; it properly signifies a hard, white, brittle, mineral substance, of a metalline nature, found at Misnia; though supposed to be only a recrementitious matter thrown off in the formation of tin, as unfit to enter its composition. There are some, however, who esteem it a metal sui generis; though it usually contains some silver. There is an artificial bismuth made, for the shops, of tin. John Quincy


  1. Bismuth

    Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery-white color when freshly produced. Surface oxidation generally gives samples of the metal a somewhat rosy cast. Further oxidation under heat can give bismuth a vividly iridescent appearance due to thin-film interference. Bismuth is both the most diamagnetic element and one of the least thermally conductive metals known. Bismuth was long considered the element with the highest atomic mass whose nuclei do not spontaneously decay. However, in 2003 it was discovered to be extremely weakly radioactive. The metal's only primordial isotope, bismuth-209, experiences alpha decay at such a minute rate that its half-life is more than a billion times the estimated age of the universe. For all but the most exotic of uses bismuth may be considered stable because of its tremendously long half-life.Bismuth metal has been known since ancient times. Before modern analytical methods bismuth's metallurgical similarities to lead and tin often led it to be confused with those metals. The etymology of "bismuth" is uncertain. The name may come from mid-sixteenth century New Latin translations of the German words weiße Masse or Wismuth, meaning 'white mass', which were rendered as bisemutum or bisemutium.


  1. bismuth

    Bismuth is a heavy, brittle, silvery-white metallic element that is primarily used in alloys and pharmaceutical compounds. It is symbolized as Bi on the periodic table and is known for its low thermal conductivity and high electrical resistance. Bismuth has an atomic number of 83 and is one of the few metals that expand upon cooling. It is only slightly radioactive and is considered one of the safest to use in various applications such as cosmetics, medicine, and industrial production.

Webster Dictionary

  1. Bismuthnoun

    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.


  1. Bismuth

    Bismuth is a chemical element with symbol Bi and atomic number 83. Bismuth, a pentavalent poor metal, chemically resembles arsenic and antimony. Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery white color when freshly produced, but is often seen in air with a pink tinge owing to surface oxidation. Bismuth is the most naturally diamagnetic and has one of the lowest values of thermal conductivity among metals. Bismuth metal has been known from ancient times, although until the 18th century it was often confused with lead and tin, which share some physical properties. The etymology is uncertain, but possibly comes from Arabic bi ismid, meaning having the properties of antimony or German words weisse masse or wismuth, translated in the mid sixteenth century to New Latin bisemutum. Bismuth has long been considered as the element with the highest atomic mass that is stable. However, it was recently discovered to be slightly radioactive: its only primordial isotope bismuth-209 decays with a half life more than a billion times the estimated age of the universe.
