The oxidation state of sodium is +1. 5. Example: Chlorine. In a chlorine molecule, the chlorine atoms are. covalently bonded. The two atoms share electrons. equally and the oxidation state is 0. 6. Example: Chlorine. The two atoms of a hydrogen chloride molecule are covalently. bonded. The electrons are not shared equally because chlorine is. more electronegative than hydrogen. There are no ions but the oxidation state of chlorine in HCl is -1 and. the oxidation state of hydrogen is +1.
