Detailed explanation-1: -That’s 2 aluminum atoms for every 3 oxygen atoms.
Detailed explanation-2: -The chemical formula for Aluminium oxide is Al2O3 which is an inorganic chemical reagent . Two Aluminium atoms bond with two oxygen atoms each to form the structure of aluminum oxide, which means it has three oxygen atoms.
Detailed explanation-3: -Answer and Explanation: Oxygen is an electronegative element and the oxidation state of oxygen is-2. The oxidation number of ‘Al’ in Al2O3 A l 2 O 3 is +3.
Detailed explanation-4: -Aluminium oxide (or Aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide.
