bismuth  (bzmth)

Symbol Bi

A brittle, pinkish-white, crystalline metallic element that occurs in nature as a free metal and in various ores. Bismuth is the most strongly diamagnetic element 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; atomic weight 208.98; melting point 271.3°C; boiling point 1,560°C; specific gravity 9.747; valence 3, 5. See Periodic Table.
