Incidentally, I'm certainly not going to sillily follow the lede here and edit the Er and Ho articles' ledes to call them the preantepenultimate and propreantepenultimate lanthanides! Double sharp ( talk) 07:53, 21 November 2013 (UTC)
There are a few odd statements which stand out. e.g.
Some very lightweight web references, and no heavyweight chemistry textbooks- e.g. Greenwood, Wiberg, Housecroft, no specialist books - e.g. Cotton , Atwood. Unreferenced wide ranging statement "Thulium reacts with various metallic and non-metallic elements forming a range of binary compounds, including TmN, TmS, TmC2, Tm2C3, TmH2, TmH3, TmSi2, TmGe3, TmB4, TmB6 and TmB12."

In all three places where a discovery date is mentioned (lede, box, and history), it says 1879, but in the Thulium(III) oxide article, the date is given as 1878. I'm going to put a similar note on that page.

Article Theodore William Richards cites John Emsley's book that says it was Richards who did this. Emsley p. 443: "In 1911, the American chemist Theodore William Richards performed 15 000 recrystallizations of thulium bromate in order to obtain a pure sample of the element and so determine exactly its atomic weight." The present article says it was Charles James and uses his 1911 paper as (primary) source. What is the correct story? I think this is a mistake in Emsley's work as the Thulium I paper mentions the operation count 15 000. jni (delete) ...just not interested 19:21, 30 January 2018 (UTC)
