Facts about the
Definition of the Element Manganese
The Element Manganese is defined as...
A gray-white or silvery brittle metallic element, occurring in
several allotropic forms, found worldwide, especially in the ores
pyrolusite and rhodochrosite and in nodules on the ocean floor. It
is alloyed with steel to increase strength, hardness, wear
resistance, and other properties and with other metals to form
highly ferromagnetic materials.

The Name Originates from the Latin word mangnes meaning magnet
Facts about the
Classification of the Element Manganese
Manganese is classified as a "Transition Metal" which are located
in Groups 3 - 12 of the Periodic Table. An Element classified as a
Transition Metals is ductile, malleable, and able to conduct
electricity and heat.

Facts and Info about
the element Argon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985
which includes the Manganese element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. The Discoverer of the Manganese element was Johann Gahn in
1774. The Standardised Periodic Table now recognises more periods
and elements than Dimitri Mendeleev knew in his day but still all
fitting into his concept of the "Periodic Table" in which
Manganese is
just one element that can be found.
