The oxidation number of Al is +3.
0 in elemental form +3 in its compounds
0 in elemental form, +3 in its compounds
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.
In pure metallic aliminium it is zero . In the majority of its compounds it is +3, e.g. in Al2O3, AlCl3, AlP

The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. Aluminum typically has an oxidation number of +3 when it forms ionic compounds.
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 aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
+3 for each Al; +4 for each C; -2 for each O
In the compound Al₂O₃, aluminum has an oxidation number of +3, and oxygen has an oxidation number of -2. This gives a total charge of zero for the compound, as it should be electrically neutral.
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.
Aluminum has only oxidation numbers.They are zero and +3.
Do you mean Aluminum Trisulfate Hectoxide? I dont know if it even exists but if it did, it would beAlS3O20 or AlO20S3
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'.
Aluminium phosphate is AlPO4 (mineral berlinite that looks a lot like quartz)- The oxidation numbers are Al +3, P +5 O-2
The oxidation number for Al in AlF3 is +3. This is because fluoride (F) has an oxidation number of -1, and the overall compound is neutral, so the oxidation number of Al must be +3 to balance the charges.
