PHONETICS

Bismuth is a brittle metal with a silvery white colour when freshly produced, but is often seen in air with a pink tinge owing to surface oxidation and is the most naturally diamagnetic element, with one of the lowest values of thermal conductivity among metals. Known since ancient times, it was often confused with lead and tin, which share some physical properties.
