Cerium is a silvery-white, ductile metal that belongs to the lanthanide series of the periodic table, with the atomic number 58 and the CAS number 7440-45-1. It is known for its relatively high melting point and is one of the most abundant rare earth elements. Cerium exhibits a variety of oxidation states, most commonly +3 and +4, which contribute to its diverse chemical behavior. It readily oxidizes in air, forming a protective oxide layer, and can react with water at elevated temperatures. Cerium compounds, such as cerium oxide, are widely used as catalysts in automotive catalytic converters and in various industrial applications, including glass polishing and as a component in phosphors for lighting. Additionally, cerium has applications in metallurgy and as an additive in certain alloys to improve their properties. Its unique characteristics make cerium an important element in both industrial and technological contexts.
