化学概念是化学学科建立和发展的基础 ,它能深刻地反映化学过程的最本质的特征。化学概念的理解和掌握不仅是学生学好基础理论、定律、公式的前提和基础 ,也是发展学生智力 ,特别是逻辑思维能力的必要条件。因此 ,学生学好化学首先要学好化学概念 ,教师要教好化学首先要重视化 The concept of chemistry is the foundation for the establishment and development of chemistry disciplines. It can profoundly reflect the most essential characteristics of chemical processes. Understanding and mastering the concept of chemistry is not only a prerequisite and basis for students to learn basic theory, laws, and formulas, but also a necessary condition for the development of students’ intelligence, especially logical thinking ability.
