Chemical terms are used throughout the entire junior middle school chemistry textbook, and the basic concept of theory and elements Compound knowledge, chemical experiments, and chemical calculations are closely linked and are the basic knowledge and important skills of junior high school chemistry. Therefore, it is a part of the key examinations in the senior high school entrance examination. The following authors have performed simple and novel types of questions in the examinations in recent years. Classification.
