Lutetium
Lutetium is named from the Latin Lutetia, the ancient name for Paris and was discovered in 1907. Lutetium is found along with the other rare-earth minerals principally in monazite and bastnasite. The metal is isolated using ion exchange and solvent extraction methods. Lutetium, like the other rare-earth metals, has a bright silver luster and is malleable and ductile. Because of its high cost, there are few practical applications for its use.
