When was lutetium first found?
Lutetium was first discovered in 1907 by the French chemist Georges Urbain. He isolated it from the mineral gadolinite, making it one of the last rare earth elements to be identified. Lutetium was later confirmed by other chemists, including the American chemist Carl Auer von Welsbach, who independently discovered it around the same time.
Where did the name lutetium come from?
Lutetium is a chemical element with the symbol Lu and an atomic number of 71. It derived its name from the ancient name of Paris which was Lutetia.
Who is the founder of lutetium?
Lutetium (Latin Lutetia meaning Paris) was independently discovered in 1907 by:French scientist Georges Urbain,Austrian mineralogist Baron Carl Auer von Welsbach, andAmerican chemist Charles James.
What is the coast for lutetium?
The coast for Lutetium is south
What city was Lutetium named after?
Lutetium was proposed as the name for the element with atomic number 71 by French scientist Georges Urbain, one of its several discoverers on 1907. It was adopted as the official name by the The Commission on Atomic Mass in 1909.
How is lutetium used?
Lutetium is used in PET scanners
What is the name of the compound LuBr3?

What is one chemical property of lutetium?
Lutetium has the oxidation state +3.
Is lutetium radioactive?
For most practical purposes, lutetium can be regarded as stable, though it is slightly radioactive. 97.41% of lutetium found in nature is stable, and 2.59% is of an isotope with a half life of 37,800,000,000 years. Like all other elements, lutetium has synthetic radioactive isotopes.
What is the price of lutetium?
Lutetium costs 42 USD for a 5 gram ingot.
What is the Bohr model for lutetium?
If you think to the electron configuration of lutetium this is: [Xe]4f14.5d1.6s2.
How was lutetium discovered?
Lutetium never is found alone. Instead, it's found in the earth's crust, along with other rare earth metals. Specifically, there's a chance of finding it where the element yttrium occurs. Lutetium is difficult and expensive to isolate and prepare. As an uncommon and costly rare earth metal, its occurrence tends to encourage its mining only in Australia, Brazil, China, India, Sri Lanka, and the United States of America.Answer by TedlyWThe rare-earth element Lutetium was first discovered as an impurity in samples of ytterbia. Six times as expensive as gold, lutetium is today found in small concentrations within the rare earth phosphate mineral monazite. Monazite has been found in many places, even in North Carolina in the U.S. But commercially viable deposits today are worked only in Brazil and southern India. Large monazite sand deposits tend to have come from the erosion of large masses of certain granites and gneiss.
