Well you should know the formula and valency of each element first,
Sodium
formula - Na
valency - +1
Oxide
formula - Oxygen - O
valency - (-2)
Since the charge of the compound has to be 0 (zero)
2 atoms of sodium (+2) are required to neutralize the effect of the one oxygen atom (-2) ----------- [2 + (-2) = 0]
Na2O

How many electrons in Sodium Oxide?
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.
What information does the chemical formula for a compound provide about the submicroscopic structure of the compound?
You can find out the elements in it, and the number of each ions of each element. Example : Na2SO4 (Sodium Sulfate) You can find out from this formula that this compound contains : 2 Sodium ions (Na2) 1 Sulfide ion (S) 4 Oxide ion (O4)
Why do you never find an individual sodium chloride molecule by itself?
Sodium chloride is an ionic compound and does not form molecules. Sodium chloride forms a crystal lattice in which each ion is surrounded by six ions of the opposite charge. The chemical formula of sodium chloride, NaCl, represents a formula unit, which is the smallest whole number ratio of ions in the compound.
How do you find the chemical formula for iron III oxide?
The name iron III oxide shows that you have two types of ion in the compound, the iron III ion (Fe3+) and the oxide ion (O2-). What you need to do is find what ratio to combine the ions in so that the positive and negative charges cancel out to zero. One way of doing this is to switch the numbers of each ion's charge, and assign it to the opposite ion, so in this case you get 2 Fe3+ ions and 3 O2- ions. So the formula is Fe2O3
What is the oxidation number of sodium carbonate?
We can find this in bleaching powder. Chlorine shows +1 oxidation number.
