Lutetium

Lutetium (Lu)

Lutetium is the 71st element in the periodic table and has a symbol of Lu and atomic number of 71. It has an atomic weight of 174.9668 and a mass number of 175. Lutetium has seventy-one protons and one hundred four neutrons in its nucleus, and seventy-one electrons in six shells. It is located in group Transition metals, period six and block f of the periodic table. Silvery-white rare-earth metal which is relatively stable in air. It happens to be the most expensive rare-earth metal. Its found with almost all rare-earth metals, but is very difficult to separate from other elements. Least abundant of all natural elements. Used in metal alloys, and as a catalyst in various processes. There are two natural, stable isotopes, and seven radioisotopes, the most stable being Lu-174 with a half-life of 3.3 years. The separation of lutetium from Ytterbium was described by Georges Urbain in 1907. It was discovered at approximately the same time by Carl Auer von Welsbach. The name comes from the Greek word lutetia which means Paris.

Lutetium sublimed dendritic and 1cm3 cube

History

French chemist Georges Urbain successfully separated lutetium from ytterbia in 1907 in Paris. Austrian scientist Carl Auer von Welsbach and American chemist Charles James also succeeded in isolating lutetium independently in the same year. Pure lutetium metal was first produced in 1953. Lutetia is the ancient name for Paris

DiscoverersGeorges Urbain
Discovery LocationFrance
Discovery Year1907
Etymology (Name Origin)Named for the ancient name of Paris, Lutecia.
Pronunciationloo-TEE-shi-em (English)
Lutetium is considered to be non toxic
Lutetium was the last natural rare earth element to be discovered

Uses

Lutetium oxide is used to make catalysts for cracking hydrocarbons in the petrochemical industry. Lutetium aluminum garnet has been proposed for use as a lens material in high refractive index immersion lithography. Lutetium is used as a phosphor in LED light bulbs. It has no practical applications.

Sources

Found with ytterbium in gadolinite and xenotime. Usually obtained from monazite sand which is ofter 50% rare earth by weight and 0.003% lutetium.
