Aluminium, Aluminum, No It Was Alumium

In the UK they say “al-yuh-min-ee-uhthinsp Aluminium, Aluminum, No It Was Alumiumm” (alu­minium). In the US we say “uh-loo-muh-nuhthinsp Aluminium, Aluminum, No It Was Alumiumm” (alu­minum). They think we sound silly. We think they sound silly. In fact the man who named the metal, Eng­lish chemist Sir Humphry Davy, orig­i­nal called it alu­mium in 1807. He later change the name to alu­minum before set­tling on alu­minium in 1812.

Ele­ment Al, with atomic num­ber 13, is the most abun­dant metal in the Earth’s crust, and the third most abun­dant ele­ment, after oxy­gen and sil­i­con. It makes up about 8% by weight of the Earth’s solid sur­face. It is too reac­tive chem­i­cally to occur in nature as a free metal. Because of this it was extremely rare and expen­sive in its pure state when the statue of Eros in Pic­cadilly Cir­cus in Lon­don was cast from the metal in 1893. At that time, both the –um and –ium spelling were in nearly equal use in the UK and the US. The name of the metal was most likely not every day as it is today.

By 1925 the Amer­i­can Chem­i­cal Soci­ety had offi­cially adopted the –um spelling. The Inter­na­tional Union of Pure and Applied Chem­istry (IUPAC) offi­cially stan­dard­ised on alu­minium in 1990. This of course has no impact on the US gen­eral pub­lic, only on the sci­en­tific community.

So who is right? Sir Davy ended his inde­ci­sive­ness with alu­minium. The IUPAC agrees, but only did so in 1990. Sir Davy picked alu­minum before alu­minium. The Amer­i­can Chem­i­cal Soci­ety agreed before the IUPAC. Sir Davy first named it alu­mium. But per­son­ally I think that sounds even sil­lier than either of the other two!

I think by now we all know that no mat­ter what we call it we know we mean that stuff used to make con­tain­ers for cheap beer.
