electron configuration
My SATII chem prep book (baron's) has this element with an orbital shell progression of [Rn]5f146d87s2... which is different from the one listed. Is there a definitive source for this? Lepidoptera 17:25, 26 July 2005 (UTC)


 * The reference is electron configurations of the elements (data page), though so far the only data for elements 105+ is merely the guesses taken from WebElements.com (which may or may not be based on a source from their bibliography). http://www.apsidium.com/elements/110.htm remarks that the takeover of the irregularity from platinum is not recommended, however it lists the 6d8 7s2 configuration as 'unconfirmed' as well. Note that I recently changed the qualifier of these guesses from "probably" to "perhaps" in the articles. As long as they're properly marked as such, any guess should be as good as the next one, unless one guess is found more educated than the other. Femto 19:13, 26 July 2005 (UTC)

atomic mass
Also, one of your sources lists the atomic mass as 281- another says 271- and my periodic table lists it as 269. With elements like this that are not found in nature, the atomic mass is not average mass of the isotopes as found in nature, but the most stable isotope. Again, is there is a definitive source for this? Elements tend to be more likely to decay if there isn't enough buffer neutrons between protons... on the other hand, the larger the atom is the more prone it is to decay as well, so I frankly have no idea which is the most correct.

 * The recent Ds-281 with its half-life in the minute range looks like the clear winner to me. Femto 19:13, 26 July 2005 (UTC)

Hoax?
"Scientists are not always serious, so some suggested the name policium for the new element, because 110 is the emergency telephone number for the German police. The element was named after the place of its discovery, Darmstadt (the GSI is located in Wixhausen, a northern portion of the city). The new name was given to it by the IUPAC in August 2003."

There's no cition. But it does sound kind of resonible and I know that scientist do have sense of humor. I'm putting the hoax tag in to make sure some looks at it and the reader doesn't use it for reaserch untill someone looks at it.---Scott3 Talk Contributions Count: 950+ 02:12, 1 September 2006 (UTC)

Concerning Hoax
Even though nobody ever really intended naming it policium, I remember reading an Article in the Darmstädter Echo which covered this story. Should have be right after they confirmed the name Darmstadtium. Maybe someone has access to their archive and can look it up for quotation. Thus I#ll remove the Hoax-Tag for now.
 * Thanks just naming it policium sounds like a hoax.---Scott3 Talk Contributions Count: 950+ 22:46, 1 September 2006 (UTC)

External links to a congress center
Under "External Links" there is a link to the new congress center called Darmstadtium. I think it should not be here, as the name is the only relation to the chemical element Darmstadtium. From my point of view it should be removed. But I'm not as used to the Wikipedia etiquette to actually do it. 217.111.26.170 (talk) 11:56, 21 November 2007 (UTC)

Why does Policium redirect here?
It's just a joke mentioned in a single book as something a class of children suggested as a name for the element. 81.152.72.174 (talk) 19:08, 28 June 2010 (UTC)

GSI location
Someone changed the description of GSI's location from "Wixhausen, a northern suburb of Darmstadt" to "Arheilgen, a northern suburb of Darmstadt" and then someone else changed that to "Darmstadt, a northern suburb of Darmstadt". Judging from the (unsourced) Gesellschaft für Schwerionenforschung article, Wixhausen is probably correct, but I've changed it to simply " Darmstadt, a northern suburb of Darmstadt" for now, since GSI's website just says Darmstadt. 28bytes (talk) 16:06, 11 January 2011 (UTC)

UUN
Hi User:Kirligross. What does "UUN" stand for (other than urine urea nitrogen, and why should UUN redirect to here? It puts this article in category:Missing redirects. Thanks, Wbm1058 (talk) 13:49, 7 December 2013 (UTC)

Hi User:Wbm1058. UUN is the prototypic name for Darmstadtium. It stands for "ununnilium", or "one-one-zero-ium", which spells out the atomic weight of this element. This and other elements heavier than it were also named similarly, and are currently in the process of being named (such as ununtritium). This element, for example, was named for the city it was found in, which was only about 20 years ago.

UUN is a common abbreviation for urine urea nitrogen, as you know. There is no article for urine urea nitrogen, but typing urine urea nitrogen automatically redirects to blood urea nitrogen. So I thought it would make sense for a redirection of UUN to happen to the same page. And that's when I saw the gap with Darmstadtium and decided that was the more significant reference.

Thanks, Kirligross (talk) 23:33, 7 December 2013 (UTC)
 * OK, thanks, I created the redirect. The article should be updated to include this information. Wbm1058 (talk) 00:06, 8 December 2013 (UTC)


 * Well, actually, "UUN" does not and has never stood for darmstadtium; "Uun" has. (Capitalization matters!) So I changed the target of "UUN" (in all caps) to blood urea nitrogen, while "Uun" currently redirects to this page. Double sharp (talk) 03:29, 8 December 2013 (UTC)
 * So should the article be updated to mention the term ununnilium (abbreviated "Uun") so we know why that redirects to here? Wbm1058 (talk) 00:23, 9 December 2013 (UTC)
 * No, I don't think so: it's an obsolete name that should never be used once a trivial name (here darmstadtium) is officially accepted. We don't have unnilquadium for rutherfordium either; that's because that was in use quite a few more years back, and nearly everyone has updated stuff. The drive to keep putting ununnilium and the ones after it in are simply because the official names were accepted more recently – though you'd think this would've stopped by now, with darmstadtium being officially accepted ten years ago(!).
 * (Additionally, try searching for how often "ununnilium" was used in real science papers during the time darmstadtium was still unnamed. I think you'll find that it was very seldom used if it all, with the most common name being "element 110" and symbol "E110" or even just "(110)" or "110". This is actually a good argument to move ununtrium, ununpentium etc. to "element 113", "element 115"...) Double sharp (talk) 02:32, 9 December 2013 (UTC)

It's amazing, I moved Ununnilium to Damstadtium back in march 03, the IUPAC in May 03 offiacly chanegd it to Damstadium, we were one of teh first sites to change it to its name. -fonzy

Lanzhou 271Ds confirmation
I don't remember whether this was in here (and I'm not even sure it needs to be, since IUPAC was satisfied long before this confirmation), but here's the paper. Double sharp (talk) 10:22, 5 January 2018 (UTC)
