Metal vs. Non-Metal

I am fairly certain that because of its characteristics, Aluminium is sometimes considered a non-metal because it shares some chemical properties with non-metals.

Toxicity

We need some clarification in the matter of aluminium toxicity. The article begins by saying that aluminium is non-toxic but later says, under the heading 'Precautions', that it is a neurotoxin. It can't be held both ways. Which is right?

I am inclined to believe that is a neurotoxin, because of something my teacher said, but a textbook would be nice. --Dolphinn_GoLeafsGo 23:36, 29 August 2007 (UTC)

Because many kitchen pots and pans are made of aluminium, the issue of toxicity is indeed an important concern. Greg Fisher 06:55, 4 October 2007 (UTC)

I've heard that elemental Al is toxic, but that since it quickly forms Al203 in air that it's not actually a huge concern in practice. This MSDS says that it's toxic if inhaled but not if ingested. Not sure whether to count that as an authoritative source or not. fsiler (talk) 23:20, 21 February 2008 (UTC)

there has been research done on this by the RIVM in the netherlands, see e.g. http://www.rivm.nl/bibliotheek/rapporten/710401022.html (and I know there is a follow up on this report which debunks the alzheimer claim, but also shows another health risk, but I need to dig somewhat deeper probably to find it) —Preceding unsigned comment added by 81.252.82.4 (talk) 11:50, 27 June 2008 (UTC)

Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Aluminum. Additional text was taken directly from USGS Aluminum Statistics and Information, USGS Periodic Table - Magnesium, 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.

Abundance

is it a coincidence that as the most abundant metal, it is the 'half' of iron, the most stable element, is there a reason or just coincidence? —Preceding unsigned comment added by 193.60.83.241 (talk) 19:42, 26 April 2008 (UTC)

on speaking to my academic supervisor, it is suggested that it is a coincidence, and its abundance is more likely related to its stability due having magic nuclei http://en.wikipedia.org/wiki/Magic_number_(physics), is this relevant to the article? —Preceding unsigned comment added by 193.60.83.241 (talk) 13:49, 30 April 2008 (UTC)

On the abundance topic, I noticed that the reference used to cite this claim (ref 1) contained no references and can not be verified. Is this a potential problem? Should we request a better citation? 72.54.98.226 (talk) 15:57, 24 July 2008 (UTC)

Ref 1 does support the sentence it is on. Wizard191 (talk) 17:22, 24 July 2008 (UTC)

Aluminium is the most abundant metal in the Earth's crust for reasons having nothing to do with nuclear chemistry but with geology and geochemistry. In fact, iron is much more abundant in the universe and in the solar system, and even on Earth if you count all the iron in the planetary core. --Itub (talk) 09:05, 30 October 2008 (UTC)

Poor?

Aluminium has a resistivity of(20 °C) 26.50 nΩ·m, compared to copper (20 °C) 16.78 nΩ·m, which is why is is often taken as a cheaper alternative for conductive wires. Could somebody please explain how that makes Aluminium a "poor" metal?? This is really ridiculous. Jcwf (talk) 02:33, 3 August 2008 (UTC)

Please read Poor metal - it's an old classification term and doesn't indicate "good" or "bad". Vsmith (talk) 02:58, 3 August 2008 (UTC)

But I've heard that Aluminium is somehow connected to evil spirits and demon posession. Can that be true? Said: Rursus (☻) 15:18, 1 December 2008 (UTC)

Aluminium 26

An article on Aluminium 26 is on my wish list for the isotope's cosmological importance: ²⁶Al is believed to have heated even protoplanets as small as Ceres and Vesta in the early solar system, its creation from supernovae in the galaxy has a great impact on how the solar system was formed, etc.. If anyone is interested enough, please create the article - otherwise I'll create it myself ... in time. Said: Rursus (☻) 13:50, 1 December 2008 (UTC)

Mining

As with lots of other metal articles the mining distribution is wrong in the amount mined and the where the mines are
