What is Lanthanum?
Lanthanum is a chemical element with the symbol La and atomic number 57. It is a silvery-white metal with a high melting point and is classified as a lanthanide in the periodic table. Lanthanum is often found in nature combined with other elements, primarily in minerals such as monazite and bastnäsite.
This element was discovered in 1839 by Swedish chemist Lars Fredrik Nilson and was named after the Greek word "lanthanein," which means "to lie hidden." Lanthanum is not found in its pure form in nature due to its reactivity, but it can be isolated through various chemical processes.
Lanthanum's Discovery
Lanthanum was first isolated by its discoverer Nilson, who used a process of fractional crystallization. This method allowed him to separate the element from its naturally occurring ores, paving the way for further research and applications of lanthanum.
Properties of Lanthanum
Lanthanum possesses several unique physical and chemical properties that make it valuable in various applications:
- Atomic Mass: 138.904 g/mol
- Melting Point: 920 °C (1,688 °F)
- Boiling Point: 3,465 °C (6,329 °F)
- Density: 6.162 g/cm³
- Electronegativity: 1.1 (Pauling scale)
Lanthanum is known for its excellent conductor properties, making it suitable for use in various electronic components. It is also relatively soft and can be easily shaped and machined.
Reactivity
Lanthanum reacts with oxygen and moisture in the air, forming a white oxide layer that protects the underlying metal. This reactivity is essential to consider when handling lanthanum in laboratory settings.
