What is Manganese? Origin / Meaning of the name Manganese
The Name Originates from the Latin word mangnes meaning magnet because pyrolusite (Mn02) has magnetic properties.

What is Manganese? Periodic Table Group and Classification of the Manganese Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Manganese is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. Elements classified as Transition Metals are generally described as ductile, malleable, and able to conduct electricity and heat.Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.

Facts about the History and the Discovery of the Manganese Element
The Discoverer of the Manganese element was Johann Gahn in 1774. Johann Gahn isolated manganese by reducing its dioxide with Carbon.

What is Manganese? Occurrence of the Manganese Element
Occurrence. Manganese is found in nature chiefly as the dioxide MnO2, called pyrolusite. In smaller amounts it occurs as the oxides Mn2O3 and Mn3O4, and as the carbonate MnCO3. Some iron ores also contain manganese.
Obtained from pyrolusite, psilomelane, rhodochrosite

What is Manganese - 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 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day 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.
