'''Manganese''' is an [[element]] in the "transition metals" class of the [[periodic table of the elements|periodic table]]. It is hard and brittle. It reacts (slowly) with water, and with acids.
'''Manganese''' is an [[element]] in the "transition metals" class of the [[periodic table of the elements|periodic table]]. It is hard and brittle. It reacts (slowly) with water, and with acids. Manganese is used in small amounts to change the propeties of steel and other useful alloys.
Manganese was discovered by [[Johann Gahn]] in 1774 by heating [[pyrolusite]] with [[charcoal]].

It is remarkable in all the other metals in that it is formed by the radioactive breakdown of magnesium isotopes, yet is still found in sufficient quantities to be useful in common, everyday processes and materials. Manganese is found in pyrolusite (magnesium) ore along with magnesium, and the two are seperated in a process similar to that of the blast furnace, due to their significantly different melting points (one melts and is tapped off while the other remains solid). <ref>Wierd and Wonderful Chemistry, William A.
