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

[edit] 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)

[edit] 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)

[edit] Hoax?

"Scientists are not always serious, so^{[citation needed]} 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)

[edit] Concerning Hoax

Even though nobody ever really intended naming it policium, I remember reading an Article in the Darmstädter Echo [1] 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)

[edit] Symbol

If the name has been changed, then why hasn't the symbol?Cameron Nedland 15:04, 15 December 2006 (UTC)

[edit] 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)
