Where did aluminum get its name?
Aluminum is given this name from a word of Latin origin “Alumen or alum”. Guyton de Morveau gave it name “alumina” in 1761. After that, it was given name “Alumium” by Humphrey Davy in 1807. After some time, he renamed it as “Aluminum” [10]. After some time conforming with named of a lot of other elements, it was renamed as Aluminium. This name was further adopted by IUPAC and is still used all over the world except in North America. So both spellings “Aluminum” and “Aluminium” are considered correct in periodic table.
