Oh and I hate how the motherland likes to call Aluminum, Aluminium. They are just adding random letters for no reason at all.
Actually, the history of the whole aluminum/aluminium split is kind of fascinating. Both versions make sense in their own way and, in the end, neither really has primacy (though, from a strictly chronological perspective, aluminium ekes out a win by appearing first in 1811 as opposed to aluminum in 1812, so far as I've found).
Both suffixes, -um and -ium, are used to denote metallic elements. The -um being part of older known elements, dating back to Latin words like ferrum (though it has occasionally been applied to more modern element names, such as platinum). Starting around 1807, however, the naming convention shifted to -ium and has been the standard ever since (titanium, uranium, and of course...
palladium). Aluminium/aluminum just happened to come along right when that nomenclature was shifting.
Aluminium is the official standard of the International Union of Pure and Applied Chemistry, though they're not especially strict about it. Whereas the American Chemical Society recognizes aluminum as the standard spelling.
So, yeah... words be crazy.
