Abstract Oxidation-reduction reaction is the core concept of chemistry. The theory of oxidation-reduction reaction is the understanding of the change of microscopic particles. During the learning process, it's necessary to identify the types of substances by studying chemical reactions from the macroscopic perspective. By studying the change of particles with the help of the microscopic modeling of reactants’ particles, as well as the microscopic modeling of derivatives’ particles, we come to know how atoms of the reactants are converted into atoms of the derivatives when an oxidation-reduction reaction occurs. After analyzing typical reactions and having a clear understanding of the nature of oxidation-reduction reaction, instead of directly studying the reaction, we can indirectly analyze the chemical reaction equation to find out if there's any transfer of electrons from the reactants to the derivatives.
