Is Al2O3 ionic compound?

Aluminium oxide (Al2O3) is not an ionic compound. It is a covalent compound.

Why is Al2O3 an ionic compound?

An ionic compound is made up of a metal and a nonmetal and has more than 1.8 as the difference in its elements’ electronegativities. Al2O3 compound comprises a metal (aluminum) and a nonmetal (oxygen). Since the difference between oxygen and aluminum is 2.0, Al2O3 is an ionic compound.

Is aluminum oxide a compound?
