Planetary Bohr Model of Manganese (Mn)
Description
Hard, brittle, gray-white metal with a pinkish tinge. Rusts like iron in moist air.
Uses
Used in steel, batteries and ceramics. The steel in railroad tracks can contain as much as 1.2% manganese. It is crucial to the effectiveness of vitamin B1.
Sources
Most abundant ores are pyrolusite (MnO2), psilomelane [(Ba,H2O)2Mn5O10] and rhodochrosite (MnCO3). Pure metal produced by mixing MnO2 with powered Al and ignited in a furnace.
Pronounciation (English)
MAN-ge-nees
