[edit] Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Argon. Additional text was taken directly from USGS Periodic Table - Argon, 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.

What is the source for the use of argon by museum conservators? I checked all these links and couldn't find it. I tried looking at some museum conservation sites but didn't see evidence that it is "commonly used." Please give citation!—The preceding unsigned comment was added by Punstress (talk • contribs).

http://www.getty.edu/conservation/publications/pdf_publications/inertgases.pdf is getting close. But no cigar. This is about using argon to kill insects in museums. However, an unqualified statement is to me it sort of makes sense as argon is noble (non-reactive) and quite common. Argon is already used in sealed glass configurations (window industry).

[edit] Suggestion

What is the function of the Tyler Craft reference? It does not seem to contribute anything and is not in the spirit of the rest of the article... 08:15, 29 January 2007


please add the number of protons, neutrons, and electrons in argon into your info. Maybe it was there already, but i didn't see it.Everything else was wonderful, thanks for all the help!!!!!

Further Suggestion: Perhaps the discovery of Argon should be given more notice on this page? —The preceding unsigned comment was added by 137.195.176.11 (talk • contribs) .

Restored the missing History section. Femto 15:26, 3 November 2006 (UTC)

The Chinese Character(traditional) of Argon is "氬"...--Jerrypp772000 00:12, 12 December 2005 (UTC)From Taiwan

Question-- the disambig at the top says that this page is about the "non-chemical element"...shouldn't that be "chemical element"?

Good catch. That was vandalism from an AOL IP a few days ago. Fixed now. --Ed (Edgar181) 18:39, 12 April 2006 (UTC)

[edit] Link suggestions

An automated Wikipedia link suggester has some possible wiki link suggestions for the Argon article, and they have been placed on this page for your convenience.
Tip: Some people find it helpful if these suggestions are shown on this talk page, rather than on another page. To do this, just add {{User:LinkBot/suggestions/Argon}} to this page. — LinkBot 10:36, 17 Dec 2004 (UTC)

== me too == i need to find some "interesting" facts about argon

argon gas blocks the passing of certain frequecy mircowave signals does anyone know how to overcome this?

[edit] Year of discovery of argon

Please check for consistency regarding the year in which argon was discovered: 1892 in science, 1894 in science, and 1898 in science. Wavelength 06:36, 20 July 2006 (UTC)

[edit] Potassium can capture a neutron to form Argon?

In the subsurface environment, it is also produced through neutron capture by 39K or alpha emission by calcium.

Potassium has 19 protons; argon has 18. If a potassium nucleus captures a neutron, it will either:

  1. Remain as a potassium nucleus (but with one more neutron), or
  2. The neutron will decay into a proton, an electron, and a neutrino, making the original nucleus into a calcium nucleus. --Bowlhover 20:23, 5 November 2006 (UTC)

[edit] Decription

If argon is a colorless gas, why the hell is there a picture of it?

[edit] RE Argon in tires

tirerack.com

"Tires are normally inflated with air (a combination of gasses comprised of about 78% nitrogen (N2), 21% oxygen (O2) and 1% argon (Ar) along with traces of other gasses)"

This very article states: "Argon is present in the Earth's atmosphere at slightly less than 1%, making it the most common noble gas on Earth."

It doesn't sound like an additive. It sounds like it's due to the fact that it is already present in teh air. Nor is it a "super expensive facy pants car" thing. As such I am removing the sentence and the *Citation needed*

[edit] GA Failed

This is very near GA, but it's terribly undercited, and needs at least one reference (that covers all information therein) for every paragraph. It's not a bad fail, though - everything else is fine - so poke me on my talk page when you've fixed it up. Adam Cuerden talk 13:42, 27 February 2007 (UTC)

[edit] Density, heat capacity

On wikipedia the density of air is listed in kg/m3, Argon is in g/liter. Some sort of standardization should be implemented.

The heat capacity of Argon is (25 °C) 20.786  J·mol−1·K−1. This is the exact same value as Krypton. Coincidence? Typo? —The preceding unsigned comment was added by 71.111.17.112 (talk • contribs).

(moved newer comments to bottom) - Not a coincidence! The molar heat capacity of all monatomic gases is the same. Femto 15:28, 9 March 2007 (UTC)

[edit] Passed GA

A good article, cited, good prose and satisfies all WP:WIAGA. Congrats. There are, however, several suggestions to improve this article for further goal: featured article, of course.

  1. Please re-read again the article to get the brilliant prose. I suggest to ask someone unfamiliar with the subject to proof-read and copyedit it. For instance, I found one very long sentence of this:
    Other uses: It is used as an inert gas shield in many forms of welding, including metal inert gas welding and tungsten inert gas welding, the gas of choice for the plasma used in ICP spectroscopy, as a non-reactive blanket in the manufacture of titanium and other reactive elements, and a protective atmosphere for growing silicon and germanium crystals.
  2. Expand more to get a comprehensive article. For instance, the history can be expanded to modern chemistry of the discovery of its applied used. For example in the surgery, who discovered it and when.
  3. Remember to explain detailed jargon to a general reader. I found this statement lacks of explanation:
    Argon’s complete octet of electrons indicates full s and p subshells. (what are s & p subshells?)
  4. Please standardize citations. Take a look at WP:CITET for some examples if you use footnotes.
  5. Please be selective on external links to avoid spam external links. It also applies for referencing to commercial sites and non-academic resources. In this kind of subject, using academic papers or journals are more preferable. Please also read WP:RS.

Okay, good luck. — Indon (reply) — 19:17, 11 March 2007 (UTC)

[edit] Change in name (really, symbol)

i notice the article mentions that argon went from A to AR. however, i can't find anything about why chemists decided to make this symbol change. anyone know? the_undertow talk 01:22, 25 March 2007 (UTC)

I have only a vague memory of reading about those debates. The single cap letter A is sometimes used as a generic variable symbol for chemical species, such as gas concentrations [A], and I imagine they wanted as little chance of confusion there as possible, especially as A would be inevitably almost always be being used alone, with no other letter to signal that it was a chemical element, part of a chemical compound. So they decided to follow the general convention for new elements (when they were finding them at the time), and extend it. This makes it symbol-correspondant with the other inert gases, too. Single-letter chem symbols have historically been reserved for old, common, and usually-seen-in-bonded-organic-configuration elements: C-H-N-O-S-P-B. The element argon didn't fit well with this crowd. SBHarris 21:25, 28 March 2007 (UTC)

[edit] 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 21:07, 28 March 2007 (UTC)

GA is not on the Wikiproject Chemistry assessment scale, and with good reason: There are no clear distinctions between B, GA, and A. There are A-level articles that are not good articles. Please do not revert.

It would be helpful if the template didn't take GA status as an actual status then. Homestarmy 21:47, 5 April 2007 (UTC)
