Manganese

Manganese ndi mankhwala omwe ali ndi chizindikiro Mn, nambala ya atomiki 25, ndi chiwerengero cha atomiki 54.9380, ndi imvi yoyera, yolimba, yowonongeka, ndi yonyezimira. Kachulukidwe wachibale ndi 7.21g/cm³ (a, 20). Malo osungunuka 1244, malo otentha 2095. The resistivity ndi 185 × 10Ω·m (25).

Manganese ndi chitsulo choyera cholimba komanso chosasunthika chokhala ndi kiyubiki kapena tetragonal crystal system. Kachulukidwe wachibale ndi 7.21g/cm ³ (a, 20 ℃). Malo osungunuka 1244 ℃, malo otentha 2095 ℃. The resistivity ndi 185 × 10 Ω · m (25 ℃). Manganese ndi chitsulo chokhazikika chomwe chimayaka mu mpweya, oxidize pamwamba pake mumlengalenga, ndipo chimatha kuphatikizana ndi halogens kupanga halides.

Manganese sapezeka ngati chinthu chimodzi m'chilengedwe, koma miyala ya manganese imakhala yofala mu mawonekedwe a oxides, silicates, ndi carbonates. Manganese ore amagawidwa makamaka ku Australia, Brazil, Gabon, India, Russia, ndi South Africa. Tizilombo ta manganese pansi pa nyanja ya Dziko lapansi tili ndi pafupifupi 24% ya manganese. Zosungirako za chuma cha manganese ore ku Africa ndi matani 14 biliyoni, zomwe zikuyimira 67% ya nkhokwe zapadziko lonse lapansi..
