用价层电子对互斥理论预测分子的结构,是无机化学教学中比较感兴趣的一个问题。很多作者来稿介绍教学经验并对此理论提出改进意见,进行切磋研讨。因限于篇幅,本刊选登郭子义同志的文章(讨论了该理论的基础、价电子对的计算方法及适用范围),并摘登何关有、刘进荣两位同志来稿的部分内容(对该理论提出了改进意见),供读者参考。 Predicting the structure of molecules by the valence electron pair mutual exclusion theory is a topic of more interest in inorganic chemistry teaching. Many authors have contributed to introduce their teaching experience and put forward suggestions for improvement on this theory for discussion and discussion. Due to space limitations, we selected articles by Comrade Guo Ziyi (discussed the basis of the theory, the calculation method of valence electron pairs and its application) and extracted some of the contributions made by two of the comrades He Guangyou and Liu Jinrong Improve the views), for readers reference.
