Article changed over to new Wikipedia:WikiProject Elements format by mav 03:03, 15 Dec 2003 (UTC). Elementbox converted 11:54, 10 July 2005 by Femto (previous revision was that of 13:23, 9 July 2005).
[edit] Information Sources
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Thulium. Data for the table was obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.
[edit] Talk
What is the element Thulium used for?And what two places that you would use Thulium in your everyday life?
Can someone explain the "History" section here? When referring to the "British king", are we talking about a British researcher named King or the actual King of Great Britain?

I've always been bothered by the description "can be cut by a knife" in the physical properties. A number of sources said this, but it just isn't true. It can be scratched with a knife, but I defy anyone to cut it (like one can cut potassium or sodium.) I spent many hours in graduate school reducing thulium metal pieces to powder, nothing short of a steel flat bastard file would work, and then only when clamped down strongly. Also, US patent 6887824, it finally issued in 2005. I'll let someone else decide if a change is warranted.
how about creating a section called "Notable characteristics" or something like that and moving this data to it(frm the introduction). "It is an easily workable metal with a bright silvery-gray luster and can be cut by a knife. It has some corrosion resistance in dry air and good ductility. Naturally occurring thulium is made entirely of the stable isotope Tm-169."--Abhishek Jacob (talk) 07:31, 22 April 2008 (UTC)
