The algebraic sum of the positive and negative oxidation numbers of the atoms in a polyatomic ion is zero 12. When an atom loses an electron during a redox reaction, its oxidation number increases. 13. Oxidation processes always result in a decrease in the oxidation number of a species. 14. A reducing agent is an electron donor. 5. In all redox reactions, electrons are transferred from an oxidizing agent to a reducing agent. 16. The anode of an electrolytic cell is the negative electrode 17. The strongest oxidizing agent present in an electric cell always undergoes a reduction at the anode
