摘要:

首先对国内化学教材在描述氧化数概念时存在的不同说法进行讨论,在此基础上建议用指定电荷数一词代替形式电荷数(或形式荷电数)和表观电荷数来描述氧化数,然后通过解读氧化数的定义,得出若干重要推论,最后介绍了我们在编写无机化学教材时对氧化数部分内容所进行的探索与尝试,并建议在无机化学、普通化学教材中引入确定元素氧化数的价层电子数法。

关键词: 氧化数, 形式电荷数, 表观电荷数, 指定电荷数, 推论, 价层电子数

Abstract:

In this paper, the different ideas about the concept of the oxidation number in domestic chemistry textbooks have been discussed. Based on this, we propose to use the term of specified charge number instead of formal charge number and apparent charge number to describe the oxidation number. Through the interpretation of the definition of the oxidation number, we draw some important inferences and finally introduce our explorations and attempts on the contents of the oxidation number in compiling the inorganic chemistry textbook, and suggest introducing the valence-shell electron number method to determine the oxidation number of elements in inorganic chemistry and general chemistry textbooks.

Key words: Oxidation number, Formal charge number, Apparent charge number, Specified charge number, Inferences, Valence shell electron number
