In 1841, Mosander extracted cerite which became didymium. In 1885 he separated didymium
two different elements giving us Neodymium. Neodymium is present in the minerals monazite, and bastasite, which are principal
sources of rare-earth elements. The metal has a bright silvery metallic luster and one of
the more reactive rare-earth metals. Neodymium quickly tarnishes in air, forming an oxide
that spills off and exposes metal to oxidation. The glass has been used in
astronomical work to produce sharp band by which spectral lines may be calibrated.
