Additional Information

History: Discovered in 1825, Ancient Greek and Roman people used aluminium as medicine and dye. First considered “Alum”, then changed to “Alumine”, which was changed into “Alumium”, which finally ended up as Aluminum, which was adopted internationally by IUPAC until they changed it to “Aluminium” to fit with most of the elements (Which end in “ium”), which was a unanimous name until the US decided to go back to “Aluminum” in 1925. Americans have continued to call it Aluminum to the present day.
