元素及其化合物知识在高中化学内容中的份量可说是半壁江山。学好这个板块,无疑有利于学生形成和体会元素周期律这一重要理论,并加以综合应用与实践;同时,这个内容是落实氧化还原反应与离子反应等重要原理的良好载体;再者,现代化课堂教学要求教师、学生、教材、媒体四要素形成最大程度 The amount of knowledge of elements and their compounds in high school chemistry can be said to be half the country. Learning this section will undoubtedly benefit students in forming and understanding the important theory of the elemental cycle law, and it will be comprehensively applied and practiced. At the same time, this content is a good carrier for the implementation of important principles such as redox reactions and ion reactions; Teaching requires teachers, students, teaching materials, and media to form the highest degree
