Description:

Lanthanum (La) is a rare-earth metal, part of the lanthanide series, with the atomic number 57. It is a soft, silvery-white metal that is highly ductile and has a metallic luster when freshly cut. Lanthanum is known for its ability to absorb moisture from the air, which causes it to tarnish and form a white oxide layer. It is not magnetic, and its properties are similar to those of other lanthanides, but it has a higher melting point and is used in various industrial applications.
