元素周期律和周期表是全部高中化学的基础,是在学生具备了对卤族、氧族、氮族等族元素知识的基础上进行讲授,然后又遵循这种科学理论进行金属各族元素的教学,这对于学生掌握系统地、完整地化学基本知识是具有特殊的重大意义。因此,元素周期律和周期表在整个化学教学中是显得异常重要的,现在仅根据我的教学实践,对这一课题的初步分析和处理情况简要的介绍如下。供大家参考,研究和批评。
Periodic and periodic table elements are the basis of all high school chemistry, is based on the students have the knowledge of halogen, oxygen, nitrogen and other ethnic groups on the basis of teaching, and then follow this scientific theory of metal elements Teaching, which is of great significance to the students to master the systematic and complete basic knowledge of chemistry. Therefore, the periodic law of the elements and periodic table in the entire chemistry teaching is very important, and now based on my teaching practice, the preliminary analysis and treatment of this issue is briefly described below. For your reference, research and criticism.
