[edit] Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Francium. Additional text was taken directly from the Elements database 20001107, and Webster's Revised Unabridged Dictionary (1913). Other information was obtained from the sources listed on the main page but was reformatted and converted into SI units.

[edit] Something fishy with the isotope chart

There is a beta decay altering the mass number. Can someone knowledgable please correct? —The preceding unsigned comment was added by 213.64.177.93 (talk • contribs) 09:04, 3 December 2006 (UTC).

Fixed accordingly. Femto 15:27, 3 December 2006 (UTC)

[edit] Liquid near room temperature

In the Mercury article it is said that francium is a liquid. But here (in the francium article) it says it's a solid. Now, I know it's no big deal because nobody's ever gotten enough of it pure for the phase to make a difference, but it might look better if it were consistent, unless there is some reason otherwise.

Since mercury includes the qualifier "at or near room temperature", no problem here. Femto 11:39, 19 December 2005 (UTC)
I would think that if any sizeable amount of francium were in say a drop of liquid, it would almost certainly vaporize because of the heat given off by its intense radioactivity. Joeylawn 04:10, 14 February 2006 (UTC)

It doesnt just vaporize, it explodes

In the Mercury talk page there's a discussion of why mercury is a liquid at room temperature; does anyone know why caesium and francium have such low melting points, and what that might suggest for the next element in the group, if it ever were produced in enough quantity for such a macroscopic property to come about? 208.23.142.201 18:23, 14 April 2006 (UTC)

If you will note the melting points of the Alkali Metals, you will see as the atomic number increases, the melting point drops. Just my 2 cents.

[edit]  ???

I am no expert in this subject, but maybe we could change the phrase "making it possibly the rarest elements in the crust, along with astatine." to "making it one of the rarest elements in the crust, next to astatine." See astatine talk page for more info.

[edit] Not entirely encyclopedic in style

"Francium has the lowest electronegativity of any element. This means it surrenders its electrons most readily. It is named after France, the country that surrenders most readily."

Har har. Hilarious, but doesn't this constitute a violation of the NPOV rule? —The preceding unsigned comment was added by 194.251.240.113 (talk • contribs).

Removed. Femto 12:12, 15 March 2006 (UTC)
You have to put it back. --84.70.131.16 18:57, 9 January 2007 (UTC)

[edit] Neither solid nor liquid

I suggest to remove the "data" like 900 K melting point of Fr. Now I only add question mark. Nobody has measured the melting/freezing point of francium or even produced any solid or liquid francium. The same about boiling point, density, thermal conductivity etc. Alternatively: add melting point of seaborgium (I suggest 4444 K, by pure extrapolation from Cr, Mo and W), ununhexium etc., if you think it is appropriate to mix measured values with quessed ones without comments. They are already well mixed in Wikipedia tables like "Melting points of the elements (data page)" 84.10.114.122 11:42, 13 December 2006 (UTC), accidental visitor, Poland

[edit] 21.8 minute half-life

i think the half-life for the most stable isotope of francium is actually 22.8 or 22.9 minutes, not just 22. G man yo 10:27, 6 February 2007 (UTC)

Reference is Isotopes of francium and its talk page. Femto 12:54, 6 February 2007 (UTC)

[edit] Picture

I may have found a rare picture of Francium here. I'll try to get permission to use it and maybe upload it onto wikipedia for this article. Might be a good idea. -- Kevin (TALK)(MUSIC) 02:48, 13 March 2007 (UTC)

Actually, that's a picture of uraninite. Don't bother. --Cryptic C62 · Talk 22:17, 29 March 2007 (UTC)

[edit] GA review

This article is very well done and well referenced. I made a few minor changes, but overall, it meets the good article criteria. The lead could use a little bit of expansion, but is sufficient for GA status. Dr. Cash 01:52, 30 March 2007 (UTC)
