aluminum+oxygenaluminum has 3 electrons to give but oxygen only needs 2, so where does that extra electron go and what kind of charge is it.explainWell it simply isnt just Aluminum + oxygen, they have different coeffficients to make it work Al is +3, whereas Oxygen is -2, so you gotta find the Least common multiple of those which is 6 so 6/3 2 and 6/2 3, so there are 2 Al for every 3 Oxygen 2x3 + 3x-2 0 Al2O3 is your compoundOther related question
