WebZnO is an ionic compound. The Zn atom donated 2 valence electrons to the O atom forming a +2 charge on it. The O atom gains 2 valence electrons from the Zn atom forming a -2 charge. It forms a strong ionic bond within Zn and O atoms due to the electrostatic force of attraction and not by a covalent bond.
