Etymology

Description

It is a white crystalline metal with a slight pink tint, belonging to group 15. It is the most diamagnetic of all metals and, excluding mercury, has the lowest thermal conductivity. Lead-free bismuth compounds are used in cosmetics and medical procedures. It burns in air and creates a blue flame. In 1753 C.G. Junine demonstrated for the first time that it was an element other than lead.

Language Of Origin

Modern Latin via Greek

Origin Of Word

From the German word. It is not currently in use.

Meaning

white mass

Symbol Origin

descriptor (colour): bisemutum

Etymological Description

The word bisemutum comes from the German word Wismuth, which may have evolved from weiße Masse, meaning "white mass" due to the element's appearance.
