初中化学教育是化学启蒙教育，教学内容虽简单，但份量不轻。涉及物质的组成、结构、性质、变化，化学量和化学用语约八十个基本概念。这些内容是化学入门的基础，是初中化学重点之一。对这些基本概念理解不清楚，掌握不准确，就很难进一步学好元素化合物知识，很难正确进行化 Junior high school chemistry education is a chemical enlightenment education, although the teaching content is simple, but the weight is not light. It covers about 80 basic concepts of composition, structure, properties, changes, chemical quantities, and chemical terms. These are the foundations of chemistry and one of the key chemical aspects of junior high school. The understanding of these basic concepts is not clear. If you do not master the concepts correctly, it will be difficult to further learn the knowledge of elemental compounds, and it will be difficult to correctly implement these knowledge.
