Bismuth


Located at Group 15 and Period 6 of the Periodic Table is a curious element which is what known as a heavy metal, similar to Lead. This is Bismuth.

First discovered by Claude François Geoffroy in 1753 and isolated by Claude François Geoffroy in 1753 too.

Apparently, Bismuth has been once discovered by a German monk called Basil Valentine in the 15th Century, where one of his writing refers Bismuth as Wismut, which is a German Phrase meaning ' white mass '.

A few years later, Wismut was Latinized to Bisetumum by Mineralogist Georgius Agricola. He reasearched on ' Bisetumum' and recognized its distinctive qualities and after that was described how it can be extracted from its ores.

It wasn't until 18th century when Bismuth was officially accepted as an metal. Works on its Chemistry was finally published in 1753 by Claude François Geoffroy. Claude François Geoffroy successfully distinguish the difference between Tin, Bismuth and Lead.

Bismuth have crystals which is called Bismuth Crystals. Bismuth Crystals grows suspiciously like a staircase, but not the plain old staircase. Instead, it looks like a multicolored staircase which is hard to describe.

Besides, Bismuth is one of a few element which its density in Solid State is lower than the density in Liquid State.

How Bismuth got its name?
Bismuth has many evolution for its name. Bismuth was first called Wismut, meaning white mass in Greek. The name was given by a German Monk called Basil Valentine. After that, a mineralogist called Georgius Agricola latinized Wismut to Bisetumum, which has the same meaning which is white mass. The final name of Bismuth is Bismuthum, given by its discoverer, Claude François Geoffroy, for his credit of discovery.

Uses
Bismuth has been used as a shimmer added into makeups in Ancient Egypt, which is at the time of the Pharaohs. Now, Bismuth is still used in Cosmetics. Bismuth is also used as a active element for curing stomach ache in a famous brand too ( Although too much doses will kill you ).
Cosmetics
