Lutetium is a chemical element; it has symbol Lu and atomic number 71. It is a silvery white metal, which resists corrosion in dry air, but not in moist air.

Lutetium was discovered in 1907. It is a rare and expensive element and is the last member of lanthanide series. It is used as a catalyst in organic chemical industry.

lutetium (Lu), chemical element, a rare-earth metal of the lanthanide series of the periodic table, that is the densest and the highest-melting rare-earth element and the last member of the lanthanide series. In its pure form, lutetium metal is silvery white and stable in air.

Lutetium. Lutetium is a chemical element with symbol Lu and atomic number 71. Classified as a lanthanide, Lutetium is a solid at room temperature.

Lutetium (pronounced as loo-TEE-shee-em) [2] is a silvery, hard, dense rare earth metal classified as a lanthanide and represented by the chemical symbol Lu [1]. It is the last chemical element belonging to the lanthanide series [3], with the most naturally abundant, stable isotope being 175 Lu (97.4% abundance).

Lutetium is the last of its family and the smallest. In size it is much nearer to yttrium and scandium, so some versions of the Periodic Table have lutetium directly under Sc and Y, preceded by the lanthanides from lanthanum to ytterbium.

2013年7月31日 · Lutetium is the last of the lanthanides, and the hardest of them. The pure metal has been isolated only in recent years and is one of the most difficult to prepare. It can be prepared by the...

Lutetium is a silvery-white rare earth metal. The metal tarnishes slowly in air and burns at 150 o C to the oxide. It is the densest and hardest of the lanthanides. It is also one of the least abundant lanthanides, however it is still more abundant on earth than silver or gold.

2022年5月22日 · Lutetium is a dense, silvery-white rare earth metal. Here is a collection of interesting element facts for lutetium or cassiopeium: Lutetium was the last natural rare earth element that was discovered. It was discovered in 1907 by three scientists, working independently from each other.

2018年5月29日 · Lutetium is a silvery white metal that is quite soft and ductile. The term ductile means capable of being drawn into thin wires. It has a melting point of 1,652 ° C (3,006 ° F) and a boiling point of 3,327 ° (6,021 ° F). Its density is 8.49 grams per cubic centimeter. Chemical properties. Lutetium reacts slowly with water and dissolves in ...
