Template:Chemical Element

Article changed over to new Wikipedia:WikiProject Elements format by maveric149. Elementbox converted 14:38, 1 July 2005 by Femto (previous revision was that of 22:48, 19 June 2005).

Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Krypton. Additional text was taken directly from USGS Periodic Table - Krypton, from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the main page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.

I moved the page from plain Krypton to Krypton (element) to reduce ambiguity with Krypton (planet), which, as the home planet of Superman, is probably far more widely known. I will amend the base page Krypton to show both options.

See discussion in Wikipedia:Disambiguation

Judging from "what links here" I say you are very wrong. The fictional planet is only going to be mentioned a small handful of times in an encyclopedia while the element is going to be mentioned many, many times. A disambiguation block is therefore the best option here - both the programming language and the planet are just a click away (just like they would be under full disambiguation). And I helped write the disambiguation policy page. --mav 20:08, 31 Jul 2003 (UTC)

Oh lighten up.

He might be blunt, but I think he's probably right here. The programming language and the fictional planet are probably less significant than the element after which they were both named. Ed Sanville 03:12, 18 December 2005 (UTC)[reply]

The speed of sound in Krypton gas as given at Allmeasures and WebElements is the speed of sound in Krypton liquid (conditions to be checked tomorrow). For the speed of sound in Krypton gas we found no available handbook value (although looking for it very hard in the second largest university library in germany). We (Projektpraktikum at the University of Constance) measured the speed of sound in 99.997 % pure krypton gas at 23°C (room temperature) and standard pressure using resonance in a closed tube and got as a preliminary result $(220\pm 1)m/s$ . (Will be rechecked when measurements are finished, some corrections for measurements in a tube have not yet been applied. For data contact johannes.ebke - at - uni-konstanz.de)

For those of you who rather believe established sources, see for example this Article from BBC. It doesn't state the exact velocity, but gives a general sense of the value to expect.

Kryptonate

Is kryptonate a molecule containing krypton or a clathrate containing krypton? From the name and the article, I would say the clathrate one, but I wanted to be sure (if they exist, what are molecules containing krypton called?). Once the definition is given, perhaps kryptonate should redirect to this article, as I don't think there's enough information for a separate article. -- Kjkolb 23:07, 17 December 2005 (UTC)[reply]

what is the origin name of krypton...and what krypton uses... — Preceding unsigned comment added by 74.116.113.241 (talk • contribs)

"Krypton" comes from the greek "krypto", meaning hidden. It is usually used in lighting, including flashlights and lasers. See the article for more. --Der yck C. 07:40, 8 March 2007 (UTC)[reply]

GA review

Good article, excellent referencing. Some suggestions:

What is abundance of krypton in extraterrestrial environments, ie other planets and the sun?
"there is evidence for KrXe or KrXe+." could do with a reference.
Reference 6 should be the original paper.

GA sweeps review

Conducting another GA review as part of the WikiProject Good Article sweep. After 6 months, I concur with the original GA review on this article, and it continues to meet the GA criteria. It's still very short, and various sections could be expanded. But overall, the content is significant enough to keep GA status. Dr. Cash 02:12, 1 September 2007 (UTC)[reply]

Lead

The lead is copied from the first few lines of the Notable Characteristics section. The lead is supposed to be a summary of the entire article, not a duplicate of a later section. --Cryptic C62 · Talk 10:21, 23 March 2007 (UTC)[reply]

That was because it was duplicated in this recent edit: http://en.wikipedia.org/w/index.php?title=Krypton&diff=116653671&oldid=116599575 . —The preceding unsigned comment was added by Squids and Chips (talk • contribs) 14:58, 23 March 2007 (UTC).[reply]

B-Class

GA class is not part of project assessment scales, and GAs are not tracked by WP Bot 1.0. The assessment level has been set to B class. --Cryptic C62 · Talk 21:09, 28 March 2007 (UTC)[reply]

Reverted. Bleh. --Cryptic C62 · Talk 03:02, 13 April 2007 (UTC)[reply]

My incorrect rollback

Sorry for the mistake. My internet connection is too slow that I pushed the button after the vandalism has been reverted. Sorry. --Der yck C. 15:17, 7 May 2007 (UTC)[reply]

Radio-isotopic dating

I have changed 'and' to 'but' in the last sentence of the first paragraph in 'Isotopes' because the use of Krypton-81 in dating waters is counter-intuitive when considering its volatility. Let me know if you think this is wrong.
