Bismuth is a brittle, silvery white post transition metal notable for low toxicity relative to other heavy metals and for colorful oxide patinas.
Properties of Bismuth | It has low thermal conductivity, high density and forms stable +3 oxidation state compounds used in catalysts and pharmaceuticals.
Uses of Bismuth | Bismuth is recovered from sulfide ores and used in low melting alloys, Pepto Bismol formulations, cosmetics and as a lead substitute in some applications.
Isotopes of Bismuth | Naturally occurring Bi 209 is effectively stable though weakly radioactive by modern measurements; bismuth compounds are generally low in acute toxicity but handled per safety data sheets.
