What is Lutetium? ;
Lutetium is a chemical element with symbol Lu and atomic number 71. It is a silvery white metal that is soft enough to be cut with a knife. It is the last member of the lanthanide series, and is the most rare of the rare earth metals. Lutetium is not found naturally on Earth, but it is distributed worldwide in small quantities in zirconium minerals. Lutetium was discovered in 1907 by Georges Urbain, Pierre-Émile Lecoq de Boisbaudran, and Charles James.
Chemical Properties of Lutetium
Lutetium is a chemical element with the symbol Lu and atomic number 71. It is a silvery white metal that is slowly tarnishing in the air. It is the last member of the lanthanide series. Lutetium is a rare earth element and is the most expensive of the lanthanides.
Physical Properties of Lutetium
Lutetium is a ductile, silvery metal that tarnishes slowly in the air. It is the densest of the rare earth metals, and its melting point is the highest of any lanthanide. It has a low reactivity and is stable in both air and water. Lutetium is the least abundant of the rare earth metals, making it very expensive.
