Manganese(Mn) atomic and molecular weight, atomic number and elemental symbolManganese is a Block D, Group 7, Period 4 element. Manganese Bohr ModelThe number of electrons in each of Manganese's shells is 2, 8, 13, 2 and its electron configuration is [Ar] 3d5 4s2. The manganese atom has a radius of and its Van der Waals radius is In its elemental form, CAS 7439-96-5, manganese has a silvery metallic appearance. Elemental ManganeseManganese is found as a free element in nature and also in the minerals pyrolusite MnO2, braunite (Mn2+Mn3+6)(SiO12), psilomelane (Ba,H2O)2Mn5O10 and rhodochrosite MnCO3. Manganese was first discovered by Torbern Olof Bergman in 1770 and first isolated by Johann Gottlieb Gahn in 1774. The name Manganese originates from the Latin word mangnes meaning magnet.

Manganese is a key metal alloy component, particularly in stainless steels. It is used to both colorize and decolorize glass. High Purity (99.999%) Manganese (Mn) Sputtering TargetPermanganate is a powerful oxidizing agent that is used in medicine and manganese oxide is used in dry cell batteries. Manganese is also added as a nutritional supplement for both human and animal consumption. Manganese is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity). High Purity (99.999%) Manganese Oxide (MnO) PowderElemental or metallic forms include pellets, rod, wire and granules for evaporation source material purposes. Manganese nanoparticles and nanopowders provide ultra-high surface area which nanotechnology research and recent experiments demonstrate function to create new and unique properties and benefits. Oxides are available in powder and dense pellet form for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Manganese is also available in soluble forms including chlorides, nitrates and acetates. These compounds can be manufactured as solutions at specified stoichiometries.

Manganese in excess is toxic, particularly the inhalation of manganese in powder or dust form. Safety data for Manganese and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the Products tab below.
