Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
Aluminium oxide is Al2O3. +3 for each Al and -2 for each O.
+1 for each Li and -2 for O
+1 for each Na -1 for oxygen (as it is peroxide)
The cobalt in the formula given has an oxidation number of +3, so that the total charge of the two cobalt ions will balance the total charge of the 3 oxide ions, which have an oxidation number of -2 each.
Sodium oxide has the chemical formula of Na2O. To find the number of electrons in this molecule, we first need to know the number of electrons for each of its constituent atoms. The number of electrons in a neutral sodium atom is 11 and the number of electrons in a neutral oxygen atom is 8. So, after doing some simple arithmetic, we find that sodium oxide has 2*11 + 1*8 = 30 electrons per molecule.
Aluminium oxide is Al2O3. +3 for each Al and -2 for each O.
+1 for each Li and -2 for O
The oxidation numbers for the atoms in magnesium oxide are: Mg+2 and O-2.
-2 for each O (oxide) -1 for Cl (chloride) +5 for P
+1 for each Na -1 for oxygen (as it is peroxide)

Fe2O3 +3 for each Fe -2 for each O
In NaBrO3 the oxidation state of sodium (Na) is 1+, the oxidation state of bromine is 5+ and the oxidation state of each oxygen atom is 2-
It is super oxide. So +1 for Cs and -1/2 for each O
Sodium Oxide Na2O is ionic. Each formula unit includes two sodium cations and one oxide anion.
