Bismuth

Bismuth is a chemical element in the periodic table that has the symbol Bi and atomic number 83. This heavy, brittle, white crystalline trivalent poor 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 less thermal conductivity. Lead-free bismuth compounds are used in cosmetics and in medical procedures.

It is a brittle metal with a pinkish hue with an iridescent tarnish. Among the heavy metals, it is the heaviest and the only non-toxic . No other metal is more naturally diamagnetic (as opposed to superdiamagnetic) than bismuth. It occurs in its native form, and has a high electrical resistance. Of any metal, it has the second lowest thermal conductivity and the highest Hall effect. When combusted with oxygen bismuth burns with a blue flame and its oxide forms yellow fumes.
