aluminum+oxygen
aluminum has 3 electrons to give but oxygen only needs 2, so where does that extra electron go and what kind of charge is it.explain

Well 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 compound

There are more exotic combinations than Al2O3, like the neutral molecule AlO2, and the anion AlO2^-, which is sometimes called "aluminate" and has a -1 charge. The AlO3^3- anion is also called "aluminate".
There is no "giving" of electrons. The bonds in AlO2 or AlO2^- are covalent. In the AlO2^- anion there is an extra electron giving it the -1 charge. Aluminum is the central atom. There is a double bond to one oxygen and a single bond to the other oxygen.
[O-Al=O]^-

That's why two aluminum atoms react with three oxygen atoms -- six electrons are given and taken

if your talking about Aluminium Oxide then there wouldn't be an extra electron because it would form like Al2O3 having three oxygen atoms and two aluminium atoms making the compound neutral
