Wiktionary
- n. A metallic chemical element (symbol Lu) with an atomic number of 71.
GNU Webster's 1913
- n. (Chem.) A metallic element separated from ytterbium in 1907, by Urbain in Paris and by von Welsbach in Vienna. It is a member of the Lanthanide rare earth group. Symbol, Lu; atomic number 71; atomic weight 174.967 [C=12.011]. Previously spelled
Lutecium .
WordNet 3.0
- n. a trivalent metallic element of the rare earth group; usually occurs in association with yttrium
Etymologies
- From Latin Lutetia ("Paris, the capital of France"). (Wiktionary)
- Latin Lutetia, ancient name of Paris, France (where it was discovered) + -ium. (American Heritage® Dictionary of the English Language, Fourth Edition)
Examples
“China accounts for 95 percent of global production and about 60 percent of consumption of rare metals, including dysprosium, terbium, thulium, lutetium and yttrium, according to the U.S.”
“Depending upon which chemist you ask, rare earth elements consist of either: the so-called lanthanide series (elements having atomic numbers from 57 [corresponding to lanthanum] to 71 [corresponding to lutetium]) or the actinide (elements 89 to 103) and lanthanide series.”

“They had a little mom-and-pop trading post on one of the lutetium-producing islands. 1 was sixteen, away at boarding school on the mainland, when a pirate attack on the mine escalated into a firestorm that destroyed the entire settlement.”
“The final pair of biologicals, significant moneymakers, were a recreational mindbender called Red Skeezix and a marine microorganism able to concentrate the rare element lutetium from juvenile water emitted by abyssal thermal vents.”
“In a similar way, lutetium decays to the element hafnium, and the relative abundances of these elements in zircon provide us information about the earlier origin of the rock host Jeff”
“It also incorporates atoms of uranium, lutetium, titanium and other rare earth elements in its crystal structure during growth.”
“Heavy Rare Earth Oxides (HREO) refers to the elements europium to lutetium, plus yttrium, expressed as oxides.”
“It should be noted that high demand for the less available heavy rare earth elements, europium through lutetium plus yttrium ( "HREE"), (particularly dysprosium europium, and terbium) is expected to exert greater pressure on prices for these specific elements.”
“The rare earths start at lanthanum, Element 57, and run to lutetium, Element 71, and if you look them over, there's a good chance you won't recognize any of them.”
“China accounts for 95 per cent of global production and about 60 per cent of consumption of rare metals, including dysprosium, terbium, thulium, lutetium and yttrium, according to the US Geological Survey.”
