在化学科学的发展进程中,逐渐形成了一套简明、严密、国际通用的符号系统,即化学用语。在初中阶段所学化学用语主要是元素符号、化学式、化学方程式等,这些又是众多化学用语的基础,所以初中阶段化学用语的学习则显得尤为重要。但学生初学化学用语时,常会感到困难,这就是使得此 In the course of the development of chemical science, a set of concise, strict and internationally accepted symbolic systems, that is, chemical terms, have gradually emerged. In the junior high school stage, the chemical terms used are mainly chemical symbols, chemical formulas, chemical equations and so on, which are the basis of many chemical terms. Therefore, the study of junior middle school chemical terms is particularly important. However, when students begin to learn chemical terms, they often find it difficult to do so
