A covalent bond occurs when atoms share outer electrons.
covalent hydrogen and ionic
There is no such substance as ai2o3 in chemistry. However, Al2O3 (with a lowercase L, not an i) is an ionic compound.
I know its Polar covalent bond, but I'm not sure you are that far in chemistry. Polar covalent means that electrons are shared unequally but still shared while and ionic bond means electrons transfered.
It is ionic
No, it is not a covalent bond. It is an Ionic bond.
