In the compound Al2O3, aluminium has an oxidation number of +3, while oxygen's oxidation number is __-2 ____.
For aluminium oxide (Al2O3) to form the ionic charges MUST balance.
Hence For the 2 aluminiums
it is 2 x 3 = +6
For the 3 oxygens
it is 3 X -2 = -6
+6 -6 = 0
So the charges balance, hence Al2O3 is neutrally charged compound and NOT an ion.

In the compound Al aluminum's oxidation number is plus 3 and oxygen's oxidation number is?
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.
What is the oxidation number of aluminum in aluminum bromide?
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.
What is the oxidation number of aluminum chloride?
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.
What is the oxidation number of Al2S3?
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.
In the compound Ni2O3 nickels oxidation number is and oxygens oxidation number is -2?
In Ni2O3, since oxygen has an oxidation number of -2 and there are three oxygen atoms, the total oxidation number contributed by oxygen is -6. Since the compound as a whole is neutral, the total oxidation number must be 0. Therefore, the oxidation number of nickel (Ni) in Ni2O3 is +3 to balance out the oxidation number from oxygen.
In the compound Al2O3 aluminum's oxidation number is plus 3 and oxygen's oxidation number is .?
In the compound Al2O3 oxygen is oxidized to minus 2. You will note that two aluminum times plus 3 is 6, and 3 oxygen times minus 2 is minus 6; thus the combination of aluminum and oxygen yields an electrically neutral molecule, since 6 - 6 = 0.
What is the oxidation number for alf3?
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.
What is the oxidation number of SiO2?
The oxidation number of silicon (Si) in SiO2 is +4. Oxygen (O) typically has an oxidation number of -2, so in this compound, the total oxidation number must equal zero. Since there are two oxygen atoms in SiO2, the oxidation number of silicon must be +4 to balance out the -4 from the oxygens.
What is the oxidation number of Al2Cr6O21?
The oxidation number of aluminum (Al) is +3, the oxidation number of chromium (Cr) is +3, and the oxidation number of oxygen (O) is -2. Therefore, in Al2Cr6O21, the total oxidation number would be +6 from aluminum, +18 from chromium, and -42 from oxygen, resulting in a net oxidation number of -18 for the compound.
In the compound Fe2O3 irons oxidation number is while oxygens oxidation number is 2?
In the compound Fe2O3, iron has an oxidation number of +3, and oxygen has an oxidation number of -2. This results in a neutral compound where the total positive charge from iron (+6) balances the total negative charge from oxygen (-6).
What is the oxidation number for C in Al4C3?
The oxidation number of carbon (C) in Al4C3 is -4. This is because aluminum (Al) has an oxidation number of +3 and there are 4 aluminum atoms for a total oxidation number of +12. This must be balanced by the oxidation numbers of the carbon atoms, which must be -4 in order for the compound to be neutral.
What is the oxidation number of aluminum in aluminum chloride?
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. Aluminum typically has an oxidation number of +3 when it forms ionic compounds.
