Neodymium, Nd

Neodymium is a chemical element with the symbol Nd and atomic number 60.

Neodymium, a rare earth metal, is present in Mischmetal to the extent of about 18%. The metal has a bright, silvery metallic luster, however, as one of the more reactive rare earth metals, it quickly tarnishes in air. The tarnishing forms an oxide layer that falls off, which exposes the metal to further oxidation. Although it belongs to "rare earth metals," neodymium is not rare at all. It constitutes 38 ppm of Earth’s crust.
