Thank you.

It will form Al2O3
When writing out compounds, we have to make sure all the +'s and -'s equal 0 within that compound

It's called a 'crossover' combination, where the 2 valence of Oxygen goes to the Al, and the 3 valence of Al goes to the Oxygen... Aluminium Oxide ... Al2O3 (The 2 and 3 are subscripts).

Aluminum oxide
Al3+ & O2- Note: you need 2 Al3+ and 3 O2- to balance the charges (6 plusses and 6 minusses):
2Al+3 + 3O-2 >>> Al2O3
