p-=!?!=-Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.+=?!?=+p-=!?!=-Historically, manganese is named for pyrolusite and other black minerals from the region of Magnesia in Greece, which also gave its name to magnesium and the iron ore magnetite. By the mid-18th century, Swedish-German chemist Carl Wilhelm Scheele had used pyrolusite to produce chlorine. Scheele and others were aware that pyrolusite (now known to be manganese dioxide) contained a new

Tā valences elektronu konfigurācija līdzīga tehnēcija un rēnija elektronu konfigurācijai, tādēļ šo elementu īpašības ir līdzīgas. Mangāna ķīmijai ļoti raksturīgas oksidēšanās-reducēšanās reakcijas. Savienojumos mangānam var būt oksidēšanas pakāpe no +1 līdz +7, kā arī negatīvas oksidēšanas pakāpes, tomēr oksidēšanas pakāpes zem +1 ir ļoti maz izplatītas.+=?!?=+h2-=!?!=-Atrašanās dabā+=?!?=+p-=!?!=-Mangāns dabā galvenokārt ir sastopams oksīda veidā (minerāls piroluzīts MnO2). Zemes garozā ir ap 0,1% mangāna un tas pieskaitāms pie samērā izplatītiem elementiem. Nozīmīg
