Manganese than one minute. The primary decay mode before the most abundant stable isotope, Mn, is electron capture and the primary mode after is beta decay. Manganese also has three meta states. Manganese is part of the iron group of elements, which are thought to be synthesized in large stars shortly before the supernova explosion. Mn decays to Cr with a half-life of 3.7 million years. Because of its relatively short half-life, Mn is relatively rare, produced by cosmic rays impact on iron. Manganese isotopic contents are typically combined with chromium isotopic contents and have found application in isotope geology and
Manganese, Minnesota Manganese, Minnesota Manganese was a small village in Wolford Township, Crow Wing County, Minnesota, United States. Manganese lies roughly north of Trommald, Minnesota. Just off County Road 30, it is perhaps best identified by its location between Coles Lake and Flynn Lake. First appearing in the 1920 census, the village was abandoned by 1960. Named after the mining of its namesake, the village first appeared as "Manganese Village" in the 1920 Census with a population of 183.
