元素化合物知识在中学化学教材中占有重元素化合物知识具有形象和抽象的二重要地位。调查了解发现，有部分中学化学教师对性。“形象”是指其实物的直观，“抽象”是指其深元素化合物知识的重要性认识不足，认为元素层次的内涵。这种关系是使学生获得元素化合化合物知识内容多 The knowledge of elemental compounds occupies heavy elements in chemistry textbooks for middle schools. The knowledge of compounds has two important roles: image and abstraction. The survey found that some middle school chemistry teachers are sexual. “Image” refers to the intuition of its physical objects, and “abstract” refers to the lack of understanding of the importance of deep-element compound knowledge and the connotation of element-level. This relationship is to enable students to obtain more elements of chemical compounds
