The oxidation number of Cl is -1 in HCl, but the oxidation number of Cl is +1 in HOCl. Answer Save. Oxidation Numbers (ON): When we assume a compound is formed from ions, we assign charges to atoms of elements in the compound, which is called the oxidation number. Assigning oxidation numbers for molecular compounds is trickier. Assign an oxidation number of -2 to oxygen (with exceptions). This Site Might Help You. This is because an ionic compound is in the form of a crystal lattice that is actually composed of these ions. The oxidation number of a monatomic ion equals the charge of the ion.
