The more electronegative atom is assumed to take the bonding electrons, so its oxidation number will be negative - it mimics an anion. The less electronegative atom is assumed to lose the bonding electrons, so its oxidation number will be positive - it mimics a cation. So, when it comes to ionic compounds, their ions have actual charges.
