Aluminium oxide is Al2O3.
+3 for each Al and -2 for each O.
In the reaction of aluminum with oxygen to form aluminum oxide (Al + O2 -> Al2O3), the oxidation number of aluminum changes from 0 to +3, while the oxidation number of oxygen changes from 0 to -2. This indicates that aluminum is undergoing oxidation, while oxygen is undergoing reduction in the reaction.
The oxidation number of NO, nitrogen oxide, is +3.
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. Aluminum typically has an oxidation number of +3 when it forms ionic compounds.
+3 for Al and -2 for O is the oxidation number for Al2O3.
The oxidation number for lithium is +1 and for oxygen is -2. In lithium oxide (Li2O), lithium has an oxidation number of +1 and oxygen has an oxidation number of -2. Therefore, the change in oxidation number for lithium oxide is -1 for lithium.
From '0' to '3'. Elemental aluminium is in oxidation state zero (0). When it combines with oxygen to form aluminium oxide , it 'looses' its three outermost electrons to oxygen. Hence aluminium metal becomes the aluminium cation (Al^3+), which is oxidation state '3'.

In aluminum oxide (Al₂O₃), the oxidation number of aluminum (Al) is +3, while the oxidation number of oxygen (O) is -2. Since there are two aluminum atoms contributing a total of +6 and three oxygen atoms contributing a total of -6, the compound is electrically neutral, confirming these oxidation states. Thus, the oxidation numbers are +3 for Al and -2 for O.
The oxidation number for lithium is +1 and for oxygen is -2. In lithium oxide (Li2O), lithium has an oxidation number of +1 and oxygen has an oxidation number of -2. Therefore, the change in oxidation number for lithium oxide is -1 for lithium.
The oxidation number of Mn in manganese VII oxide is +7. This is because oxygen typically has an oxidation number of -2, and there are two oxygen atoms in manganese VII oxide, giving a total oxidation number of -4. To balance the compound's charge of 0, manganese must have an oxidation number of +7.
The oxidation number of Al is +3.
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. This is because each chlorine atom has an oxidation number of -1, and there are three chlorine atoms bonded to the aluminum atom, resulting in a total charge of -3 for the chlorine atoms. For the compound to be neutral, the aluminum atom must have an oxidation number of +3.
The oxidation number of aluminum in aluminum bromide is +3. In this compound, aluminum has transferred three electrons to bromine to form the ionic bond, resulting in an oxidation state of +3 for aluminum.
The oxidation number of potassium in potassium oxide is +1. Potassium is an alkali metal that typically has a +1 oxidation state when it forms compounds.
