Information Sources[edit]

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Lutetium. Additional text was taken directly from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table were obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but were reformatted and converted into SI units.

Least abundant element?[edit]

The occurrence section states that this element is "the least abundant of all naturally-occurring elements". The article on Astatine also makes this claim, when it says "Astatine is the rarest naturally occuring element". They can't both be the rarest natrally occuring elements.

I think this has already been corrected, but lutetium is ranked as about as abundant as silver. Scott Tygett Sept. 2007

Rare at all?[edit]

There's a contradiction between this article and the current article for rare earth elements. That article says that lutetium is 200 times more abundant than gold; this article says it "is the least abundant of all naturally occurring elements." Could someone clarify and update both articles? Thanks. Jeneralist 17:33, 17 September 2006 (UTC)

I just looked up the price of Lu. It can be purchased in Kilo quantities for $3.29/gram (99.9%); much cheaper than gold. Scot.parker 16:47, 13 January 2007 (UTC)

That is a pretty wide spread, from $75 to $4?? Can anyone confirm this?

I just visited the Los Alamos website and their web page and this now have one glaring omission: lutetium has the highest quantum spin number of the elements.

"Quantum spin" is something I do not completely understand. Someone knowledgeable might argue that referring to lutetium's use in tomography implies this, but lutetium being at the top of the pyramid, you'd think it would deserve mention. The spin is image-able and measureable. To be blunt, it looks like the Los Alamos material substantially weakened this page.

If I remember the material correctly, lutetium is also the heaviest white element, according to a Molycorp pamphlet. Scott Tygett

OO71Lu176 is also noted to be unique in having the only stable OO isotope greater than OO57La138, and thus is the heaviest stable OO isotope.WFPM (talk) 15:52, 27 December 2008 (UTC)
Also note that of the 8 stable OO isotope nuclides, 5 occur at the beginning of a chemical series.WFPM (talk) 18:02, 28 December 2008 (UTC)

Why lutetium is a lanthanide[edit]

Lutetium is a lanthanide because the elements that belong or don't belong to certain chemical groups is determined by international convention, and the appropriate body for determining this convention is IUPAC and IUPAC says in the second to last page here that it is a lanthanide. Do not confuse "lanthanide" with "f-block." Lutetium is the only d-block lanthanide until IUPAC changes its collective mind. Also, see the discussion here: Talk:Periodic_table_(standard).

Wow, this article lives up to it's B+ rating. Pass. It may need a more through Peer Review before going to WP:FA. "Decent," I would say Excellent. :)

File:Lutetium sublimed dendritic and 1cm3 cube.jpg to appear as POTD soon[edit]

Hello! This is a note to let the editors of this article know that File:Lutetium sublimed dendritic and 1cm3 cube.jpg will be appearing as picture of the day on September 27, 2012. You can view and edit the POTD blurb at Template:POTD/2012-09-27. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! howcheng {chat} 22:05, 26 September 2012 (UTC)

Picture of the day
Lutetium

Pieces of sublimed dendritic lutetium, as well as an argon arc remelted 1 cm3 cube of it for comparison. Lutetium is a hard, silvery-white rare earth metal which was discovered as an impurity in the mineral ytterbia. It is rare and expensive, and has few specific uses.
