为进一步提高化学教学质量,根据个人参加我省高等学校招生考试化学试卷质量分析和对试题的钻研,以及平日教学实践的体会,认为在依据大纲,全面讲清讲透教材的基础上,必须狠抓以下几个方面的内容:第一、物质结构与周期律:物质的性质是它的结构的反映,要了解物质的性质就必须从它的结构出发,而物质的制法、用途,又都是受它的性质所制约的,所以关于物质结构方面的知识,应该说是非常重要的。在中学化学教学中应该要求学生掌握原子核的组成及核外电子的分布规律,原子序数1～20号的各元素的原子结构简图,各主族元素原子的最外电子层和次外电子
In order to further improve the quality of chemistry education, according to the individual’s participation in the examination of the quality of chemistry examination papers in colleges and universities in our province, as well as the study of the test questions, and the experience of the teaching practice on weekdays, we believe that in order to comprehensively explain the teaching materials thoroughly, it is necessary to Grasping the following aspects: First, the material structure and the cycle law: The nature of a substance is a reflection of its structure. To understand the nature of a substance, one must proceed from its structure, and the substance’s method of manufacture and its use It is constrained by its nature, so knowledge of the structure of matter should be said to be very important. Students should be required to master the composition of the nucleus and the distribution of the electrons outside the nucleus in the chemistry teaching in middle schools. The atomic structure diagrams of the elements of the atomic number 1 to 20, the outermost electrons and the sub-electrons of the atoms of each main group element
