Herein, how do you find the oxidation number of Al in al2o3?
Secondly, is Al2O3 a neutral compound?
Since the overall charge of a compound must always be equal to zero (neutral), we need 2 aluminum atoms and 3 oxygen atoms in order to balance out the charge and make the compound neutral. This means that the chemical formula for aluminum oxide is simply Al2 O3. That’s 2 aluminum atoms for every 3 oxygen atoms.
What is aluminum oxidation?
The process of aluminum corrosion is known as oxidation. The resulting aluminum oxide is a thin, hard layer that actually protects the metal from further corrosion. Aluminum oxide appears as a powdery white or dull gray coating.

What is the oxidation number of Al in Al OH 3?
What is the oxidation number of Al in Al OH 4?
when I do the oxidation state forAl in Al(OH)4- I get -3 and the answer is +3.
What is the oxidation number of Al in Al s?
What is the oxidation number of Al in al2s3?
What is the oxidation number of alcl3?
Therefore the oxidation states are +3 and -1. Since its not in options we can consider option D as answer assuming that…. 3 electrons lost by Al atom and 3 electrons accepted by Cl atoms. Thus option D +3, -3 is our answer.
