The chemical name is Manganese and the chemical
symbol is Mn. The origin of the word Manganese
comes from the latin word of "magnes" which means magnet.
Manganese's properties were found to be an element
by Scheele, Bergman and a few others, but was
actually isolated by J.G. Grahn in Stockholm,
Sweden, 1774.
Pure Manganese is isolated by putting manganese
sulphate(MnSO4)through electrolysis(the production
of chemical changes, by way of a electric current
through an electrolyte(a non-metal conductor, in
which the current is carried by movement of ions)).
The atomic number of Manganese is 25, also the
atomic mass is 54.938049.
Manganese is a solid at 25 degrees Celsius with a
very metallic composure. It has a melting point of
1246°C or 2275°F and a
boiling point of 2061°C or 3742°F. It
also has a 7.2 density.
Manganese can change from one composition to another
through either human or natural procedures. But
Manganese does not completely dissappear or
dissolve in any situation or enviroment. Though
some compounds that include Manganese can
dissolve, most of those compounds are found in lakes,
streams, rivers, in low levels. Manganese
slowly corrodes in moist air and dissolves in acid.
Manganese increase the quality of many different
alloys, including some ferromagnetic alloys. Though
it has to go through special treatment to
become ferromagnetic to be part of those alloys. But
it increases the alloys it's in, many different
ways(i.e.strength, toughness, flexibility).
It's also used in the compound used for
drying black paint. Manganese is responsible for
the colour of true amethyst, the colour of it
comes from the manganese in it. It is needed in
digestion and is the 12th most abundant
element in the Earth's crust.
