The lattice arrangement … WebSodium oxide must have the N a O 2 formula unit because oxygen ions have the 2 − charge state and sodium ions have the 1 + charge state. The ionic lattice can only have zero electric charge if there are two sodium ions for every oxygen ion. This implies that option E is wrong, and option A must be correct.
