Its been bugging me for years and i want to know why they say aluminum and not aluminium like it is spelt in the Oxford English dictionary and more importantly the universal periodic table, accepted by all countries, does anyone know why? I would like all opinions on this matter, if possible, thank youAluminum okorder.com/...
