n. Symbol Bi
A brittle, crystalline, highly diamagnetic metallic element with a very low thermal conductivity and a pinkish-white luster, used in alloys to form sharp castings for objects sensitive to high temperatures and in various low-melting alloys for fire-safety devices. Atomic number 83; atomic weight 208.98; melting point 271.3°C; boiling point 1,564°C; specific gravity 9.78; valence 3, 5. See Periodic Table.
(Elements & Compounds) a brittle pinkish-white crystalline metallic element having low thermal and electrical conductivity, which expands on cooling. It is widely used in alloys, esp low-melting alloys in fire safety devices; its compounds are used in medicines. Symbol: Bi; atomic no: 83; atomic wt: 208.98037; valency: 3 or 5; relative density: 9.747; melting pt: 271.4°C; boiling pt: 1564±5°C
[C17: from New Latin bisemūtum, from German Wismut, of unknown origin]
a brittle, grayish white, red-tinged, metallic element used in the manufacture of fusible alloys and in medicine. Symbol: Bi; at. wt.: 208.980; at. no.: 83.
[1660–70; < New Latin bisemūtum, Latinized form of German Wissmuth (now Wismut)]
Symbol Bi A brittle, pinkish-white, crystalline metallic element that occurs in nature as a free metal and in various ores. Bismuth has the greatest resistance to being magnetized of all metals and has the highest atomic number of all stable elements. It is used to make low-melting alloys for fire-safety devices. Atomic number 83. See Periodic Table.
