高一化学第三章“物质结构元素周期律”在中学化学教材体系中具有突出的地位和重要的作用.统编全日制十年制中学化学课本的教材体系是以物质结构知识为主线的.而高一化学第三章包括了这一理论主线的主要内容,在整个化学教材中起了承前启后,统领全书的作用. “物质结构元素周期律”章共有10节,按教材内容的内在联系,可分为三个教学单元.本文讨论的“化学键”相当于课本中的第六节至第十节.
The third chapter of “Chemical Structure and Elemental Periodicity Law” of Gaoyi Chemistry has prominent status and important role in the middle school chemistry teaching material system. The textbook system of the textbook of the full-time, ten-year high school chemistry textbook is based on material structure knowledge. The third chapter of Gaoyi Chemistry includes the main content of this theoretical line. It has played a role in the entire chemistry textbook and has taken over the role of the whole book. The “Cycle of Material Structure Elements” chapter consists of 10 sections, according to the internal link of the teaching materials. It can be divided into three teaching units. The “chemical bonds” discussed in this paper are equivalent to the sixth to tenth sections of the textbook.
