Weird that Americans want to go with Aluminum when there’s also Americium, Berkelium, and Californium. Not to mention Deuterium, Helium, Iridium, Lithium, etc..
If we're going to be consistent with other elements, it should be Aluminum, that way it matches Molybdenum and Platinum, the only 2 other elements ending in "um" (please don't check this).
