Neodymium chemical element Britannica

Neodymium (Nd), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Neodymium is a ductile and malleable silvery white metal. It oxidizes readily in air to form an oxide, Nd2O3, which easily spalls, exposing the metal to further oxidation. The metal must be stored
