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)[reply]

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)[reply]

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)[reply]

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)[reply]

The article states, in all its content, the radioactivity of the element and the use of it. But beside its radioactivity I suppose that it has also physical, chemical properties. Is it that way that with whichever other element it "associates" the radioactivity will not disappear?

Yes, all uranium compounds are radioactive because they contain radioactive uranium atoms. Double sharp (talk) 04:54, 13 March 2019 (UTC)[reply]

"Along with all elements having atomic weights higher than that of iron, uranium is only naturally formed in supernovae." The National Academy of Sciences (NAS), NASA, et al., have claimed now for decades that elements heavier than iron did not form via supernovae. The NAS with NASA published Eleven Science Questions for the New Century with questions #10, "How were the heavy elements from iron to uranium made?". Why did they ask this (contrary to the certainty of our WP article)? First, there are insufficient neutrons in a supernova to create a large quantity of neutron-rich heavy elements. Second, telescopes looking at actual supernovas do not detect the heavy element spectral emissions that they should if they had been created there. The current favored theory is neutron star collisions or neutron star black hole collisions. Bob Enyart, Denver KGOV radio host (talk) 23:01, 27 June 2019 (UTC)[reply]

@BobEnyart: Thank you for pointing this out. The article indeed was misleading in this sense, as r-process nucleosynthesis can occur either in supernovae or neutron star mergers. I amended the article to account for this, and I may expand upon it later. ComplexRational (talk) 23:55, 27 June 2019 (UTC)[reply]
