结构化学在中学化学总复习中是重要知识点之一,也是难点之一。《考试说明》中明确要求“对原子、分子、化学键等微观结构,有一定的三维的想像能力”,笔者认为在复习中可通过“点”、“线”、“面”、“体”四个字去理解、揭示结构化学认识规律。“点”指的是构成物质的基本微粒:原子,分子,离子; Structural chemistry is one of the important points of knowledge in the review of chemistry in middle school, and it is also one of the difficulties. “Examination Notes” clearly require that “microscopic structures such as atoms, molecules, and chemical bonds have certain three-dimensional imagination capabilities”. The author believes that in the review, “points,” “lines,” “faces,” and “body” can be used. Words to understand and reveal the cognitive laws of structural chemistry. “Point” refers to the basic particles that make up a substance: atoms, molecules, ions;
