[XAP]Bob wrote:That one's easy - the full word for Al isn't...Sir Humphry made a bit of a mess of naming this new element, at first spelling it alumium (this was in 1807) then changing it to aluminum, and finally settling on aluminium in 1812. His classically educated scientific colleagues preferred aluminium right from the start, because it had more of a classical ring, and chimed harmoniously with many other elements whose names ended in -ium, like potassium, sodium, and magnesium, all of which had been named by Davy.
The International Union of Pure and Applied Chemistry (IUPAC) officially standardised on aluminium in 1990, but those who live north of Mexico haven't bothered.
IUPAC recognises aluminum as an alternative. Pronunciation follows.
