71
Atom. weight: 174.967
Density: 9.842
Class:
Rare Earth Metal
Melting point: 1663°C
Boiling point: 3395°C

Discoverer: Gheorges Urbain
Place: Paris, France
Year: 1905

Discovered in 1907 by G. Urbain in Paris, France, and, independently, by C. James at the University of New Hampshire, USA. Lutetium is the hardest, densest and one of the rarest of the lanthanide group of elements (it has an abundance of 0.51 ppm in the earth's crust). It is found in some of the less common minerals (e.g. gadolinite and xenotime) and is difficult to isolate. Applications of lutetium tend to be limited to research only.

Lutetium -  precision density-standard cube 1cm3 NEW!

Using finest materials, each density cube was lapped to 10x10x10mm by a mechanical engineering company with an accuracy of 0.01 millimeter. Each one separately ground and polished it represents the theoretical density of the respective element by its weight. The weight is not affected by the laser inscription. Information such as element symbol, name and density is durable burned at the surface. Each element even shows its specific characteristis in colour and reaction with the laser. Altogether 25 elements are planned in a complete set in a wooden case.
