'''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|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.
