13 Facts About Lutetium

Lutetium is a chemical element with the symbol Lu and atomic number 71.

Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths.

Lutetium is generally considered the first element of the 6th-period transition metals by those who study the matter, although there has been some dispute on this point.

Lutetium was independently discovered in 1907 by French scientist Georges Urbain, Austrian mineralogist Baron Carl Auer von Welsbach, and American chemist Charles James.

Lutetium chose the name lutecium for the new element, but in 1949 the spelling was changed to lutetium.

Lutetium is not a particularly abundant element, although it is significantly more common than silver in the earth's crust.

Lutetium usually occurs in association with the element yttrium and is sometimes used in metal alloys and as a catalyst in various chemical reactions.

Lutetium metal is known to react with the four lightest halogens to form trihalides; all of them are soluble in water.

Lutetium metal is then obtained by reduction of anhydrous LuCl3 or LuF3 by either an alkali metal or alkaline earth metal.

Lutetium salts are known to occur together with other lanthanide salts in nature; the element is the least abundant in the human body of all lanthanides.
