化学用语是用来表示物质的组成、结构和变化规律的符号。它具有国际通用、简明直观、书写简便的特点,使用化学用语,也有助于学生抽象思维能力的培养和发展。化学用语表述了物质的组成、结构、变化,如原子、分子、离子要用元素符号、化学式和离子符号来表述,物质的变化要用化学方程式来阐述,化学计算也要以化学用语为基础等等。显而易见,化学科学的各个领域都要使用化学用语,
Chemical terms are symbols that represent the composition, structure, and changing patterns of matter. It has the international common, concise and intuitive, easy to write features, the use of chemical terms, but also help students abstract thinking ability of the training and development. Chemical terms describe the composition, structure and changes of substances, such as atoms, molecules, and ions to be expressed by symbolic symbols, chemical formulas and ionic symbols. Chemical changes should be formulated using chemical equations. Chemical calculations must also be based on chemical terms Wait. Obviously, chemical terms must be used in all fields of chemical science,
