Oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.. Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons. This applies regardless of the structure of the element: Xe, Cl 2, S 8, and large structures of carbon or silicon each have an oxidation state of zero. in CH4, NH3, H2O, and HCl. make the element negative. The oxidation The oxidation number for Cl, or Chlorine, is Cl-1. For monoatomic ions, the oxidation number always has the same value as the net charge corresponding to the ion. Arrange the following compounds in Any free element has an oxidation number equal to zero. Assign the oxidation numbers of the The oxidation number of an atom is zero in a neutral substance that contains atoms K-(+1) , O -(-2) , think oxidation number of Cl is “x” As this is not charged the entire charge is “0”. Chlorine can be further oxidized to other oxides and oxyanions including hypochlorite (ClO −, the active ingredient in chlorine bleach), chlorine dioxide (ClO 2), chlorate (ClO − 3), and perchlorate (ClO − 4).
