What are some common properties of neodymium?

Answer 1

Neodymium, a rare earth metal, was present in the classical mischmetal at a concentration of about 18%. Metallic neodymium has a bright, silvery metallic luster, but as one of the more reactive lanthanide rare-earth metals, it quickly oxidizes in ordinary air. The oxide layer that forms then peels off, and this exposes the metal to further oxidation. Thus a centimeter-sized sample of neodymium completely oxidizes within a year.

Neodymium commonly exists in two allotropic forms, with a transformation from a double hexagonal to a body-centred cubic structure taking place at about 863 °C.

Answer 2

Neodymium is a rare earth element with a silvery metallic appearance. It is known for its high magnetic strength, making it a key component in magnets used in various industrial applications. Neodymium is also relatively reactive, tarnishing easily in air and requiring special handling to prevent oxidation.
