Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
Q: Doesn't the spelling aluminum predate aluminium? A: Yes, and alumium predates both. IUPAC uses both, but prefers aluminium. Q: I still think aluminium sounds funny/odd/jarring. A: Someone from another country would say the same about aluminum. Q: I have new, pressing information that leads me to believe the spelling should still be changed.
Davy suggested the metal be named alumium in 1808 [30] and aluminum in 1812, thus producing the modern name. [29] Other scientists used the spelling aluminium; the former spelling regained usage in the United States in the following decades. [31]
aluminium vs aluminum: aluminum is the prevalent spelling throughout North America; however, in scientific literature aluminium should be used, as recommended by the International Union of Pure and Applied Chemistry, or IUPAC. (The two spellings also have different pronunciations.)
aluminium: aluminum: The spelling aluminium is the international standard in the sciences according to the IUPAC recommendations. Humphry Davy, the element's discoverer, first proposed the name alumium, and then later aluminum. The name aluminium was finally adopted to conform with the -ium ending of some metallic elements. [105]
This is especially true for elements names aluminium, sulfur, caesium (which have variant spellings). So even when article aluminium is written in US-English, the US-spelling "aluminum" is not used. When IUPAC has not provided or sanctioned a name, a common or descriptive name is used (metalloids, post-transition metals).
But why not resolve this dispute by calling aluminium aluminum aluminium aluminum the thirteenth element on the periodic table "niluntrium" (derived from the IUPAC systematic element names. And it would have the symbol "Nut", which is pretty much how I'd sum up this dumb debate. --116.14.27.127 14:32, 3 June 2009 (UTC)
That's because it's a spelling and pronounciation issue for aluminium/aluminum, not just spelling. Notice how there's been little fighting on the spelling of caesium/cesium, as people who use the alternate spelling can accept IUPAC's judgement. :) --Ed 11:11, 25 July 2006 (UTC) Oppose IUPAC spelling should take precedence.--
