Does one mean stoichiometrically, or structurally as in a crystal lattice.

In the example, Na prefers +1 valence state, while O prefers -2, so the compound in that case would be Na2O. For ionic compounds the positively charge cation is usually electropositive, and tends to give up electrons readily to the negatively charged anion, which is electronegative, i.e. has an affinity for electrons.

Also, see discussions about ionic compounds.

One has to understand the difference between ionic and covalent bonds

How did you figure out Na2O from Na+¹ + O-²?
