Terbium Metal (Noun)
Meaning
A separate group of related lanthanides, including terbium, europium, gadolinium, and sometimes dysprosium.
Classification
Nouns denoting substances.
Examples
- Terbium metal is used in the production of phosphors, which are materials that emit light when excited by an electric current.
- The separation of terbium metal from other lanthanides is a complex process due to their similar chemical properties.
- Terbium metal is a silvery-white, slightly malleable, and ductile element that is highly reactive with air and water.
- In the context of the lanthanide series, terbium metal is often grouped with europium, gadolinium, and dysprosium due to their similar atomic radii.
- The extraction of terbium metal from its ores is typically done through a process of solvent extraction, followed by electrolysis or reduction with a more reactive metal.
