元素化合物知识是中学化学知识体系的重要组成部分。按照《化学科考试说明》的规定,元素化合物知识点共有100多个知识点,而且这部分知识多数是描述性的,内容零碎、分散和繁杂,需要记忆的东西较多,难以掌握和运用。根据高考化学试题的要求,针对该专题知识点多的特点,下面谈谈复习元素化合物这一大专题的基本思路。我们在学习元素及化合物性质时,可以从以下几个方面入手。1依靠基本理论为指导,来减轻学生的记忆负担元素化合物知识包括金属和非金属两部分,是高中化学的基础知识之一。知识特点是作为化学基本概念、原理、实验和计算的
The knowledge of elemental compounds is an important part of the chemical knowledge system in secondary schools. According to the “Chemistry Exam Notes”, there are more than 100 knowledge points in the knowledge of elemental compounds, and most of this knowledge is descriptive. The content is piecemeal, scattered and complicated, and there are many things that need to be memorized to be difficult to grasp and use. According to the requirements of college entrance examination chemistry questions, for the characteristics of the topic more points, the following talk about the basic idea of the topic of the compound elemental review. We learn the elements and the nature of the compound, you can start from the following aspects. 1 Rely on the basic theory as a guide to reduce the memory burden on students Elemental compounds including metal and non-metallic parts, is one of the basics of chemistry in high school. Knowledge is as a chemical basic concepts, principles, experiments and calculations
