The oxidation number of a Group VIIA element in a compound is -1, except when that element is combined with one having a higher electronegativity. 1. What is the element that is oxidized? Oxidation Numbers Questions 1. (b) In a redox reaction, the oxidation number increases for a reducing agent. 13 terms. + Oxidation Number = +1 MnO 4-oxygen’s oxidation number = -2 4 oxygens total = -8 sum of ox. Fe 2. Chemistry. Step 2: Examine the oxidation number of the carbon on each side and add the necessary electrons. Lead, however, is most often found in the II oxidation state, with the IV state being fairly unstable. The reducing agent, or reductant, is an element that loses or "donates" electrons (i.e. Aq ) of 2 units a decrease in the compound SnCl4 //www.vedantu.com/chemistry/oxidation-state-of-group-17-elements '' > Solution -...
