Etymology

Description

It is a gray and brittle transition metal. It is extremely electropositive and can combine with nonmetals when heated. It was discovered by Scheele in 1774.

Language Of Origin

Greek via Latin, Italian and French

Origin Of Word

Changed from the group Magnesia negra (see Magnesium)

Meaning

Magnesia

Symbol Origin

descriptive

Etymological Description

From the Latin word "Magnesia", which eventually entered Greek. Magnesia evolved into the words "mangenese" in Italian and "manganèse" in French.

Production & Use

Sources

The most abundant ores are pyrolusite (MnO2), psilomelane [(Ba,H2O)2Mn5O10] and rhodochrosite (MnCO3). The pure metal form is obtained by mixing manganese dioxide (MnO2) with powdered aluminum and firing it in a furnace.

Uses

It is used in steel, batteries and ceramics. Steel in railroad tracks can contain as much as 1.2% manganese. Vitamin B1 is essential for it to be effective.
