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 crack through the concrete sidewalks. In the 1990s, a majority of the land was purchased. It is now privately owned and has a "no trespassing" sign posted on the gate of the southeastern part of the city. Presently, the area is consumed entirely by the growth of natural vegetation. Although the grid pattern of roads remains, the roads have either disintegrated or have been completely overtaken by grass, trees, and shrubs. The sheer height of the trees expose what has become of land once occupied by numerous buildings. Manganese is a classic example of a "ghost town." Manganese, Minnesota Manganese
