Bismuth is an element that has the symbol Bi and atomic number 83. It is in the "pnictogen" (phosphorus group) column of the periodic table.
This heavy, brittle, white crystalline trivalent metal has a pink tinge and chemically resembles arsenic and antimony. Of all the metals, it is the most naturally diamagnetic, and only mercury has a lower thermal conductivity. It has generally been considered to be the last stable, non-radioactive element on the periodic table. But its one "stable" isotope was recently shown to be radioactive with half-life of over 1019 (19 quintillion) years.
Bismuth compounds are used in cosmetics, medicines, and in medical procedures. As the toxicity of lead has become more apparent in recent years, alloy uses for bismuth metal as a replacement for lead have become an increasing part of bismuth's commercial importance.
Alloys with bismuth can have very low melting points, and are used as triggers in fire sprinkler systems.
