[edit] Information Sources
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Boron. Additional text was taken directly from USGS Periodic Table - Boron, 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.
[edit] Talk
What the hell is "continental pizza crust"? (Isotopes section) ;Bear 04:26, 2004 Nov 11 (UTC)

[edit] possible Graffitti?
In the external links, the last one is for 'zeroman' - seems to have no relation to Boron whatsoever. Is this a Wiki version of tagging?
[edit] Amorphous Boron: green or black?
In the first paragraph, it says that amorphous boron is a black powder. Later it states that amorphous boron is used in pyrotechnics du to its distinct green color. Which one is true? (129.132.168.19) --- (flame color, article been updated since then) Femto
[edit] Boiling point
I've seen it stated as 4000 °C, 4200 °C, and 3864 °C. Also that boron sublimates at 2550 °C, which is not mentioned in the article. Which is correct? Or does boron have both a normal boiling point and a sublimation point, or what? Femto 14:10, 4 Apr 2005 (UTC)
- You forgot this article, which lists it as 4200 K (which doesn't agree, even with rounding, with any of the values you mentioned). Gene Nygaard 14:23, 4 Apr 2005 (UTC)
- Yikes. (that's all) Femto 14:39, 4 Apr 2005 (UTC)
This sentence from the article is hard to understand, perhaps even meaningless: "The latter effect species preferential removal of the 10B(OH)4 ion onto clays results in solutions enriched in 11B(OH)3 may be responsible for the large 11B enrichment in seawater relative to both oceanic crust and continental crust." Perhaps it should be: "The last effect, the preferential removal of 10B(OH)4 ions onto clays resulting in solutions enriched in 11B(OH)3, may be responsible for the large 11B enrichment in seawater relative to both oceanic crust and continental crust." Or something like that.
[edit] Bulk modulus
Where has the bulk modulus figure (320 GPa) come from? Several papers [eg PRB 47 (1993) 7668, Comp. Mater. Sci. 17 (2000) 127, PRL 89 (2002) 245501, PRB 67 (2003) 174116] list it as closer to 200 GPa, though there's some spread in the numbers. —The preceding unsigned comment was added by 132.229.116.34 (talk • contribs) .
- Reference is elastic properties of the elements (data page), we mostly rely solely on WebElements.com there. Any references welcome. I have expanded it with http://dx.doi.org/10.1103/PhysRevB.47.7668 (have no access to the data of other refs) and changed this article to the 185 GPa of β boron from there.

[edit] Elemental Boron
Any idea how this is produced? It has seen some research as a high-energy rocket propellant, in eg the Blackstar spaceplane.
THis is utter speculation and should not be included in Wikipedia
[edit] Boron: Electron eater?
I don't know if this is vandalism, but is certainly waxing melodramatic; "in an attempt to quench boron's insatiable hunger for electrons." CompIsMyRx 16:44, 25 March 2006 (UTC)
[edit] Only Non-metal Usually Oxidized
"Also, boron is the only non-metal that usually is oxidized (losing electrons) in reactions."
Is this true? Usually is unclear. Sulfur is often oxidized, so are phosphorus and selenium. Borides (reduced boron compounds) do exist. Boron is, however, the least electronegative non-metal. I will replace the statement with, "Also, boron is the least electronegative non-metal, meaning that it is usually oxidized (loses electrons) in reactions." --71.227.190.111 04:50, 31 July 2006 (UTC)
[edit] Name origin
The origin given seems to be for borax. I read that boron was a contraction of borax and carbon, due to the similarity in appearance of the latter to amorphous boron. This origin is given in both the book Life Science Library: Matter and the book Nature's Building Blocks by John Emsley. --71.227.190.111 05:13, 31 July 2006 (UTC)
[edit] Periodic Table
So, uh... What's the deal with the weird-looking periodic table? Couldn't someone just go find a regular one? Similarly, I've noticed about five different forms of the table floating around Wikipedia -- wouldn't it help to stick to one design, for the sake of consistency (not to mention headache prevention)? 71.219.51.225 06:57, 18 August 2006 (UTC)
- The tables in the infoboxes? It's a regular wide version, what is weird about it? If you want to contribute to standardization efforts, there's Wikipedia:WikiProject Elements and its talk page. Femto 11:16, 18 August 2006 (UTC)
[edit] Argument against merging "boriding."
It's just one more use for boron. What are we going to do, merge "burning" into "oxygen"? Boriding deserves to keep its own stub (although we can mention it as a use here, also). SBHarris 00:51, 2 November 2006 (UTC)
