Uranium 2+ now known in soluble molecular species

There are now two published examples of uranium in the 2+ oxidation state, as characterized structurally (X-ray) and specatroscopically (NMR, magnetics, etc). I think it is reasonable to change the sentence "A few solid and semi-metallic compounds such as UO and US exist for the formal oxidation state uranium(II), but no simple ions are known to exist in solution for that state." to be current. The two literature examples are: 10.1021/ja406791t (JACS, W.J. Evans) and 10.1002/anie.201402050 (Angewandte, K. Meyer). — Preceding unsigned comment added by 192.12.184.7 (talk) 22:16, 16 March 2015 (UTC)

This comment has stood for just under two years. I would like to update the relevant section/sentences soon. — Preceding unsigned comment added by 12.19.178.2 (talk) 16:49, 19 December 2016 (UTC)

Where does Uranium originate ?

I can't find anything about this in the article, there should be an explanation of creation mechanism. Supernovas ? Rcbutcher (talk) 10:57, 2 February 2017 (UTC)

From the "Occurrence" section: "Along with all elements having atomic weights higher than that of iron, it is only naturally formed in supernovae." Primordial thorium and uranium are only produced in the r-process (rapid neutron capture), because the s-process (slow neutron capture) is too slow and cannot pass the gap of instability after bismuth. Double sharp (talk) 11:31, 2 February 2017 (UTC)

I've moved that info to separate "Origin" subsection to make it easy to find as it was buried in a section covering where it is found. Rcbutcher (talk) 02:20, 4 February 2017 (UTC)

According to Dr Donald Trump's definition,"Uranium is this thing called nuclear weapons. And other things. Like lots of things are done with uranium. Including some bad things."

Should be edited to include where Uranium was discovered, the article already lists date of discovery and by whom, it should include location. 165.29.122.157 (talk) 18:09, 6 March 2017‎

Please clarify what you want added. The article already says it was discovered in the lab in Berlin. RudolfRed (talk) 19:11, 6 March 2017 (UTC)

Decay chains

Hi

in https://en.wikipedia.org/wiki/Uranium#Natural_concentrations there are several links that suggest to link to a description of the actual decay chain: "The decay series of 235U, which is called the actinium series, ...." "Uranium-234, which is a member of the uranium series (the decay chain of uranium-238), ..." But all three link in these sentences end in https://en.wikipedia.org/wiki/Decay_series That is frustrating if you actually want to see the decay chain.

Please change this. No, I can't. I'm in a rush.2A02:8108:88C0:3E8:B4E7:1316:67A:F1D7 (talk) 00:03, 3 May 2018 (UTC)

damn it. forgot the headline. Also here in this sentence: ", decaying through the "Uranium Series" of nuclear decay, " — Preceding unsigned comment added by 2A02:8108:88C0:3E8:B4E7:1316:67A:F1D7 (talk) 00:06, 3 May 2018 (UTC)

I have added a header for this. The decay series article includes all four actinide decay chains; I have changed the links to point directly to the relevant sections. Double sharp (talk) 06:54, 3 May 2018 (UTC)

19 June 2018

Hi (sorry if I do something wrong; I'm new here) This is just a very small request and it's not that big of a deal but I noticed it and think it should be changed so people don't get confused. At the start, it says "It is a silvery-white metal...", but later in the box thing under General properties in the Appearance section it says "silvery grey metal...". Uranium is actually a silvery-grey metal so the second sentence should change from "It is a silvery-white metal in the actinide series of the periodic table." to "It is a silvery-grey metal... ". I don't think this needs sources... (am I right??) --Mshe40 (talk) 10:52, 19 June 2018 (UTC)
