Definitions and meanings of "Manganese"

What do we mean by manganese?

A gray-white 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. Atomic number 25; atomic weight 54.938; melting point 1,246°C; boiling point 2,061°C; specific gravity 7.21 to 7.44; valence 1, 2, 3, 4, 5, 6, 7. cross-reference: Periodic Table. noun

Chemical symbol, Mn; atomic weight, 55. A metal having a remarkable affinity for, and in some respects a close resemblance to, iron, of which it is an extremely frequent associate. noun

An element obtained by reduction of its oxide, as a hard, grayish white metal, fusible with difficulty (melting point 1244° C), but easily oxidized. Its ores occur abundantly in nature as the minerals pyrolusite, manganite, etc. Symbol Mn. Atomic number 25; Atomic weight 54.938 C=12.011. noun

A heavy black powder MnO2, occurring native as the mineral pyrolusite, and valuable as a strong oxidizer; -- called also familiarly manganese. It colors glass violet, and is used as a decolorizer to remove the green tint of impure glass. noun

A metallic chemical element (symbol Mn) with an atomic number of 25. noun

A hard brittle grey polyvalent metallic element that resembles iron but is not magnetic; used in making steel; occurs in many minerals noun

A metallic chemical element (symbol Mn) with an atomic number of 25, not a free element in nature but often found in minerals in combination with iron, and useful in industrial alloy production.

A single atom of this element.
