论文部分内容阅读
中学化学教材内容是以结构化学为主线而编排的。原子结构和分子结构都属于结构化学的知识。原子结构、分子结构与元素周期表等知识的关系很密切。周期表是元素周期律的具体表现形式。周期表的形式有多种,应用最广泛的是长式周期表。我在中学化‘学教学中体会到,指导学生自行编制元素周期表是大有益处的。通过自制周期表,一方面能使学生充分熟悉元素周期表的结构,又能系统而巩固地掌握化学基础知识,同时也会使学生在分析和归纳过程中受到一定的思维训练。现将我指导学生自行编制元素周期表的步骤及其应用简介如下。不当之处请批评指正。
Secondary chemistry textbook content is structured by the main line of chemistry and layout. Both atomic structure and molecular structure belong to the knowledge of structural chemistry. The relationship between atomic structure, molecular structure and periodic table knowledge is very close. The periodic table is a concrete manifestation of the periodic law of the elements. The periodic table has a variety of forms, the most widely used is the long-form periodic table. I learned in secondary school teaching, guiding students to prepare their own periodic table is of great benefit. Through the self-made periodic table, on the one hand enable students to fully familiar with the structure of the periodic table, but also a systematic and solid grasp of the basics of chemistry, but also make students in the process of analysis and induction by a certain train of thought. Now I guide students to compile their own periodic table of elements and their applications are as follows. Please comment on the improper correction.
