化学用语是中学化学基础知识的重要组成部分,是化学计算的基础;是学习化学的重要工具,也是初中学生学习化学遇到的难点,还是学好化学的关键。只有抓住了元素符号、化学式、化学方程式这一化学用语主线,掌握了化学用语这一工具,才能用简明的符号正确表达物质及其变化过程,才能加深对化学基础知识
Chemical language is an important part of the basic knowledge of chemistry in middle school, which is the basis of chemical calculation. It is also an important tool to learn chemistry. It is also a difficult problem for middle school students to learn chemistry. It is also the key to learning chemistry well. Only by grasping the chemical symbolism of chemical elements, chemical formulas and chemical formulas and mastered the chemical jargon can we correctly express the substance and its changing process with concise symbols in order to deepen the understanding of basic chemical knowledge
