Nov 01, 2015 · 1 Answer. The oxidation number of chlorine can be -1, 0, +1, +3, +4, +5, or +7, depending on the substance containing the chlorine. The most common oxidation numbers are -1 (as in HCl and NaCl) and 0 (as in Cl2 ). But chlorine can have other oxidation numbers, for example: Chapter 4 - Ionic Bond Introduction Atoms can gain or lose valence electrons to become ions. Ions can be monatomic, such as Ca 2+ and Cl 1-, or polyatomic, such as NH 4 1+ and CO 3 2-.An ionic bond is the electrostatic (Coulombic) force of attraction between two oppositely charged ions. Ions and how they bond are the topic of this chapter.The chlorine atom in chlorine dioxide has an oxidation number of +4. For this reason chlorine dioxide accepts 5 electrons when it is reduced to chloride. When we look at the molecular weight, chlorine dioxide contains 263 % 'available chlorine'; this is more than 2,5 times the oxidation capacity of chlorine. Chlorine exists in all odd numbered oxidation states from −1 to +7, as well as the elemental state of zero and four in chlorine dioxide (see table below, and also structures in chlorite). [11] Chlorine typically has a −1 oxidation state in compounds, except for compounds containing fluorine , oxygen and nitrogen , all of which are even more electronegative than chlorine.
