Lutetium(Lu) is the one the lanthanide elements with an atomic number 71. It is a silvery-white rare earth metal that slowly tarnishes in air. Lutetium is the densest and hardest metal among rare earth metals. Being the least abundant lanthanides, lutetium is more abundant on earth than silver or gold metals. In compounds lutetium exists in its trivalent state and its halides are colorless. Lutetium readily dissolves in acids forming solutions containing colorless lutetium complexes with 7-9 water molecules ([Lu(OH) 8.2 ] 3+ ). The discovery of this metal was made independently by several scientists in 1907. They were French chemist Georges Urbain, Austrian mineralogist Baron Carl Auer von Welsbach and American chemist Charles James. However, due to Georges Urbain’s earlier publications the element was named by him as lutecium and today we got lutetium since in 1949 the spelling was changed. Mostly and as commercially lutetium is separated from mineral called monazite. It is never f...

* Like promethium, Lutetium is also an element which is not that old. Lutetium Rare Earth Element was the last natural rare earth element to be discovered by Charles James and Georges Urbain. Lutetium’s atomic weight is 174.97 and its chemical symbol is Lu. *Lutetium rare earth element's name comes from Lutetia which is latin name of Paris. *This silvery-white rare earth element is considered to be non-toxic and Lutetium rare earth element is included in lanthanide element family. *Lutetium rare earth element’s reaction with air happens slowly and after 150◦C, it burns to the oxide. *In lanthanide element family, Lutetium is the densest and hardest one. *Lutetium is mostly used in petrochemical industries for cracking hydrocarbons. And lutetium is also very useful in cancer therapies. *Lutetium rare earth element's isotopes are so effective reveal the age of ancient meteorites, blue stone...i.e * Lutetium rare earth element also has applications for petroleum ref...
