==Element Picture Progress==
{{shortcut|WP:Element_Picture_Progress}}
Here is the current progress of locating pictures for the remaining elements without images, and what users can possibly do to help the search. Feel free to add your own findings (remember to sign), or discuss them on this page's talk page. See [[Wikipedia:WikiProject_Elements/Pictures|here]] for more details.

===[[Wikipedia:WikiProject_Elements/Pictures#Pictorial_table|Poor quality]] images: [[Nitrogen]], [[Calcium]], [[Barium]],[[Promethium]]===

These elements already have images but they are not the highest quality. These elements aren't too rare, so it shouldn't be too hard to find other pictures. Google's probably the best bet here but it may also be worth asking one of Wikipedia's element photographers (a [[User:Alchemist-hp|certain person]] comes to mind) to see if they can get a better photo. Barium may be slightly harder but the ideas are the same. [[User:Nicholasb07|Nicholasb07]] ([[User talk:Nicholasb07|talk]]) 08:51, 23 March 2012 (UTC)
:Alchemist-hp replaced the (formerly bad) Sr image and said (a year ago) that he would try to take better pictures of Ca, Sr, Ba, Se, Sn, Hg and Tl, but only Sr was done. The Se and Tl images were changed; the Sn image is still the same but is now rated as "B" (instead of "C") on the scale at [[WP:ELEM/PIC]]. He never mentioned N.

Manganese is also a rather low-quality picture (285x283 px). Why are we not using the image that Alchemist-hp has provided in the alternatives section? That's very high-quality (5424x3368 px). [[User:Jacob S-589|Jacob S-589]] ([[User talk:Jacob S-589|talk]]) 23:50, 25 September 2013 (UTC)
:It's far too oxidized to be able to claim to show the pure element. Ni also has the same problem (though to a lesser degree). [[User:Double sharp|Double sharp]] ([[User talk:Double sharp|talk]]) 11:04, 26 September 2013 (UTC)

===[[Promethium]]===

Promethium is not an easy image to find, however, out of all the elements without a picture, it is one of the two most likely to have a picture discovered. The only pictures floating around the place are of [[:File:Pm,61.jpg|promethium chloride]] and [[:File:Pm_oxide.jpg|promethium oxide]], but not the metal itself. This is likely because the metal is not used for anything, it's hard to make, and there's no need to make any. [[Wikipedia_talk:WikiProject_Elements/Pictures#Promethium_Image|I recently discovered]] a paper by a scientist who first made promethium metal, but it contained no images. So I'm out of ideas, we're just going to have to wait around for this one, doing the occasional Google search every now and then. [[User:Nicholasb07|Nicholasb07]] ([[User talk:Nicholasb07|talk]]) 08:51, 23 March 2012 (UTC)

Check Google Images, as there may be a few images of promethium floating around. [[User:Gcchemistry|Gcchemistry]] ([[User talk:Gcchemistry|talk]]) 22:12, 7 December 2012 (UTC)

:There doesn't appear to be anything. [[User:Double sharp|Double sharp]] ([[User talk:Double sharp|talk]]) 13:35, 3 January 2013 (UTC)

::This appears to be a genuine picture of the metal: [http://www.theodoregray.com/periodictable/Samples/061.2/index.s12.html]. [[User:Nergaal|Nergaal]] ([[User talk:Nergaal|talk]]) 16:34, 25 January 2013 (UTC)
:::Looks like a watch hand, probably with Pm paint applied; see also the RGB company version (further down that page)... [[User:Double sharp|Double sharp]] ([[User talk:Double sharp|talk]]) 13:50, 23 March 2013 (UTC)
Update:A picture has been discovered, but is is very low quality.Updates now on the Poor Quality Images section

===[[Astatine]]===

Astatine is the least likely element to ever get any image whatsoever. At least for all the elements below 100, there is ''something.'' A picture of a compound, a picture of a very small amount, or an energy emission image. But for astatine, there is ''nothing.'' All we know is that astatine is apparently a black solid, which according to the sources I've found is only a prediction. [http://gotexassoccer.com/elements/085At/At.htm This page] basically sums up the best we're going to get: either a picture of uranium ore, which contains an extremely miniscule amount of astatine, or a picture of a discovery paper, showing that astatine was detected rather than observed directly. There is a very small chance that a light/heat emission photo may show up, similar to that of [[:File:Francium.jpg|francium]], but this is only a depiction of the energy due to radiation and will not qualify for an infobox picture. Only time (and occasional googling) will tell, I wouldn't get your hopes up on this one. [[User:Nicholasb07|Nicholasb07]] ([[User talk:Nicholasb07|talk]]) 08:51, 23 March 2012 (UTC)

===[[Francium]]===

There are techinically a few pictures of francium floating around, 2 of which are on the element's article (the 300,000 atom heat one and the 200,000 atom light one), and 2 [http://gotexassoccer.com/elements/087Fr/Fr.htm here] (the black and white one of 1000 atoms, and the discovery paper). However, none of these depict the atom directly, they are just images of the heat and light emitted by radiation. Technically, a photo captures the emission of light, so one would think that these photos are fine, but in reality, all you're seeing is energy, not francium. As for a picture of the actual element, even an optimistic person like myself would realise this is impossible given the element's extremely short half life. I'm happy with what we have and I wouldn't encourage spending time looking for better images. [[User:Nicholasb07|Nicholasb07]] ([[User talk:Nicholasb07|talk]]) 08:51, 23 March 2012 (UTC)

===[[Radium]]===

We already [[:File:Radium226.jpg|have]] quite a nice infobox picture of radium (as well as the radium watch-hand pictures in the article), and as far as I know, this is the only picture of the pure element itself. The only issue is that it is quite a low resolution. It was taken by [[User:Grenadier|this]] user, who unfortunately hasn't been on Wikipedia since 2010. You could try contacting him for a higher res picture, but this has already been done, and no reply was obtained. Until then, Google is our friend. [[User:Nicholasb07|Nicholasb07]] ([[User talk:Nicholasb07|talk]]) 08:51, 23 March 2012 (UTC)
:I would be very interested to find out exactly how this image was obtained. If the user ever returns to Wikipedia, we should try to find out. In my opinion, a non-free image that gives detailed information about how it was created is better than a free image that gives very little info (e.g. how did the user obtain the radium?) [[User:Double sharp|Double sharp]] ([[User talk:Double sharp|talk]]) 10:16, 24 March 2012 (UTC)

===[[Actinium]]===

Actinium is likely to be one of two elements that will next recieve a picture. Actinium can be made in reasonable amounts, and has a decent half-life of 21 years. There is only one picture of anything actinium related so far, and it's an image of it's [[:File:Actinium_sesquioxide.jpg|oxide]]. However, if it's oxide can be photographed, there's no reason why the metal can't. You can even [http://www.isotopes.gov/catalog/product.php?element=Actinium&type=rad&rad_product_index=1 buy actinium] (albeit probably a microscopic amount) if you've got the cash (this is the only place I've found that sells it. All the other elements they sell have some form of picture). So it's just a matter of finding an image that's already out there (and I wouldn't mind betting there is, somewhere), or either waiting for an image to be created (anyone fancy buying some? Just kidding!) [[User:Nicholasb07|Nicholasb07]] ([[User talk:Nicholasb07|talk]]) 08:51, 23 March 2012 (UTC)

Update: I think the actinium that the site sells is actually a compound (nitrate). Not important, but just don't go buying some :) [[User:Nicholasb07|Nicholasb07]] ([[User talk:Nicholasb07|talk]]) 08:51, 23 March 2012 (UTC)

I'm unsure if this is a real image of Actinium [http://www.webqc.org/periodictable-Actinium-Ac.html|here]. I know we had this image (or one like it) in the infobox years ago. I'm assuming that we took it out for a reason; there's no source or anything on the page. However, Actinium has been noted to glow blue. The same website also has a better quality image of Radium (if it is indeed real). Most of the other images seem reliable (Tc, Fr, Pm2O3). [[User:Jacob S-589|Jacob S-589]] ([[User talk:Jacob S-589|talk]]) 23:45, 25 September 2013 (UTC)

This image (http://science.energy.gov/np/highlights/2012/np-2012-07-a/) appears fairly reliable, more so than the one above, mainly because it gives an isotope (225Ac) and because it's a .gov site. [[User:Jacob S-589|Jacob S-589]] ([[User talk:Jacob S-589|talk]]) 01:21, 7 October 2013 (UTC)
:I don't trust webqc – no reliable sources were given. The other webpage seems very reliable. (I will upload it.) [[User:Double sharp|Double sharp]] ([[User talk:Double sharp|talk]]) 07:02, 7 October 2013 (UTC)
::Uploaded at [[:File:Actinium.jpg]] and inserted into the [[actinium]] infobox. [[User:Double sharp|Double sharp]] ([[User talk:Double sharp|talk]]) 12:54, 7 October 2013 (UTC)
Update:A Picture has been found

===[[Fermium]]===

It was never expected that we would get a picture for fermium. It's the last element that can be produced macroscopically, but the chances of finding a picture were next to nothing. Still, I decided to email the [[Oak Ridge National Laboratory]], the world's largest producer of fermium, to see what they had. They replied saying they had one photo with the tag "fermium", but it was just a man working in a lab; there was no fermium at all in the image. I gave up hope... but a few days later, I got an email from another person, who had the email forwarded to him. He also said he had one picture, but this time, it was the real deal: he sent me [[:File:Fermium-Ytterbium_Alloy.jpg|this]]. It's an alloy of fermium with a rare earth, and there's so little fermium in it, you probably don't see any in the picture anyway. But it's a picture of a fermium alloy, so that's good enough for me. He said that had they collected all the fermium they had ever made, they ''may'' have been able to obtain an image. So, while I don't think this image can be improved, it may be worth emailing them once every 6 months or so to see if they ever end up producing an image, however unlikely that may be.

===[[Transfermium_element|Transfermium elements]]===

It isn't possible to get an image of a trans-fermium element because they can only be produced in microscopic amounts. A possible addition to the [[fermium]] article (the "Isotopes" section) is how the absence of beta-decaying Fm isotopes, sometimes known as the "fermium wall" (see [http://cyclotron.tamu.edu/smp/The%20Heaviest%20Elements%20in%20the%20Universe.pdf]) prevents the formation of heavier elements by neutron capture.
