化学用语是用来表示物质的组成、结构及变化规律的一种特殊语言,它是学习化学的重要工具。表示物质组成的有:元素符号、离子符号、化合价、化学式;表示物质结构的有:原子结构示意图、离子结构示意图;表示物质变化的是化学方程式。化学用语贯穿整个初中化学教材的始终,它是化学基础知识的重要组成部分,是引导学生学习化学的一种基本工具。化学用语形象直观、言简意赅、使用简便,又能表达确切的科学含义,是进行
Chemical language is a special language used to represent the composition, structure and variation of matter. It is an important tool for learning chemistry. Said the composition of the material are: the elements of symbols, ionic symbols, valence, chemical formula; that material structure are: the atomic structure diagram, the ionic structure diagram; material changes that the chemical equation. Chemical terms throughout the junior high school chemistry textbooks has always been, it is an important part of chemical basic knowledge, is to guide students to learn chemistry as a basic tool. Chemical language image is intuitive, concise, easy to use, but also to express the exact scientific meaning is to carry out
