Bismuth (Bi)

Bismuth is the 83rd element in the periodic table and has a symbol of Bi and atomic number of 83. It has an atomic weight of 208.98040 and a mass number of 209. Bismuth has eighty-three protons and one hundred twenty-six neutrons in its nucleus, and eighty-three electrons in six shells. It is located in group fifteen, period six and block p of the periodic table. White crystalline metal with a pink tinge, belongs to group 15. Most diamagnetic of all metals and has the lowest thermal conductivity of all the elements except mercury. Lead-free bismuth compounds are used in cosmetics and medical procedures. Burns in the air and produces a blue flame. In 1753, C.G. Junine first demonstrated that it was different from lead.

History

Bismuth has been known since ancient times, so no one person is credited with its discovery. The element was confused in early times with tin and lead because of its resemblance to those elements. In 1753, French chemist Claude François Geoffroy demonstrated that this metal is distinct from lead and tin. From the German Weisse Masse, meaning white mass

Discoverers	Known to the ancients.
Discovery Location
Discovery Year
Etymology (Name Origin)	German: bisemutum, (white mass), Now spelled wismut.
Pronunciation	BIZ-meth (English)

Bismuth is considered to be non-toxic

Bismuth has unusually high electrical resistance for a metal

Uses

Bismuth is used in producing malleable irons and is used as a catalyst for making acrylic fibers. Bismuth oxychloride is used in cosmetics, as a pigment in paint for eye shadows, hair sprays and nail polishes. It has also been used as a replacement for lead in shot, bullets and less-lethal riot gun ammunition. Main use is in pharmaceuticals and low melting point alloys used as fuses.

Sources

It can be found free in nature and in minerals like bismuthine (Bi2O3) and in bismuth ochre (Bi2O3)
