化学式是继元素符号之后,学生学习的第二种化学用语,是“双基”的重要组成部分。学生只有掌握了化学式,才能进一步学习化学方程式及有关化学式的计算。可见化学式承上启下,掌握化学式与否,直接影响着其他化学用语和其他化学知识及技能的学习。所以初中阶段化学式的学习特别重要。然而很多学生在学习化学式时常常会觉得难学,在书写化学式时,会出现各种各样的错误,那么怎样才能学好化学式呢?可以从以下几个方面着手。一、熟练书写元素符号元素符号是学习化学式的基础,学习元素符号
Chemical formula is following the elemental symbols, the second chemical language students learn, is an important part of “double base ”. Only students master the chemical formula, to further study the chemical formula and chemical formula calculation. Visible chemical formula on the Kai, master the chemical formula or not, a direct impact on other chemical terms and other chemical knowledge and skills learning. Therefore, junior high school chemistry learning is particularly important. However, many students often find it difficult to learn chemical formulas. When writing chemical formulas, various mistakes can occur. So how can we learn chemical formulas? From the following aspects. First, the skilled writing elements Symbolic symbols are the basis for learning chemistry, learning elements symbols
