Europium[edit]

Voting period is over. Please don't add any new votes. Voting period ends on 4 Aug 2010 at 02:39:53 (UTC)

Original - Europium, element 63, a lanthanide, and the most reactive of the rare earth metals. Due to its extreme reactivity, it can only be found in anything resembling purity when kept under an atmosphere of a non-reactive gas such as (in this case), the noble gas argon. We see it here in a glove box, a device used to manipulate chemicals and other objects which either need a special atmosphere, or which are too hazardous to put in the same room as the experimenter.
Reason
There are some minor technical issues; however, Europium is exceptionally reactive, and can only be seen in anything resembling purity as we get here: In a glove box, in an atmosphere made up entirely of a noble gas, in this case, argon. As the issues with this image are only those necessary to taking this image, I believe that the exceptional difficulty of getting this image at all, combined with the image... actually being quite good, make this FP-worthy.

  • Support If this is the best Alchemist can do, then this is the best anyone can do. Greg L (talk) 03:10, 26 July 2010 (UTC)[reply]
  • Comment The image in the infobox is of similar purity, and while it's not as good as this one, I think it proves that a better shot is at least possible. Quality can probably be improved and composition (especially background) can definitely be improved. Makeemlighter (talk) 05:27, 26 July 2010 (UTC)[reply]
  • Oppose. I'm not pleased to be the one to say it, but this one's just not quite there. A damn difficult element to photograph, no doubt about that, and I've no doubt that this image is a fantastic addition to the article, but I don't think it is feature worthy.

  • Oppose: This is one of Alchemist-hp's earlier photographs, before he perfected his technique. I don't think the drawbacks of this image are due to the element itself; with another sample, I'm sure Alchemist-hp could produce his usual excellent work. (Not to imply that it would be trivial for him to do so, only that this one isn't up to par and could be.) Maedin\talk 11:46, 26 July 2010 (UTC)[reply]
    • It was for me only a single and very rare chance in the past to take a photo from a large, clean and high purity (and very expensive) Europium sample. I think this is a very valued photo, but not a futured?!? I can't take a similar and better photo today, sorry. My current samples are only a small pieces under argon in glas vials (=ampoules). --Alchemist-hp (talk) 23:23, 26 July 2010 (UTC)[reply]
an other typical europium sample an air: total oxidized, lying on aluminized foil.

  • Comment Given that this sort of photograph entails such extraordinary technical effort, you deserve an “A” for effort. I liked the image because europium looks so cool. Notwithstanding the herculean effort, the word seems to be developing that the end result is not FP quality as far as the technical aspects go. Indeed, when I zoom all the way, it is not in sharp focus at the back of the sample. That was something I was willing to forgive because it has to be in a glove box under argon. I can understand the reasoning of those who object. I know it seems a bit like “Go stand 1000 feet from ground-zero at the Trinity test explosion and take the picture again (and then run really fast).” Like I said: it’s way-cool. Moreover, you should get ten barnstars for making Wikipedia the beneficiary of your extraordinary efforts. Greg L (talk) 23:37, 26 July 2010 (UTC)[reply]
