论文部分内容阅读
一、试题分析“物质结构与性质”试题以选考题的形式出现,分值为15分,全国统一考试大纲对这部分内容要求不高,都是较为基础的知识点,涉及原子结构和元素的性质、化学键与物质的性质、分子间作用力与物质的性质。要求学会根据某些物质的结构特征解释一些物理现象,能够运用价层电子对互斥理论或杂化轨道理论推测简单的分子或离子的空间构型。这类题目考查方式很灵活,通常直接给出元素或者提供一些信息推断元素为何种,再进一步深入考查其他
First, the test questions “material structure and nature ” test questions in the form of exam questions, the score is 15 points, the National Uniform Exam outline of this part of the content is not high, are more basic knowledge points, involving the atomic structure and The nature of the element, the nature of the chemical bond and substance, the interaction between molecules and the nature of the substance. It is required to learn how to interpret some physical phenomena based on the structural features of certain substances and to infer the spatial configuration of simple molecules or ions using valence electron vs. mutex theory or hybrid orbital theory. Such topics examination method is very flexible, usually given directly to the elements or provide some information to infer what kind of element, and then further examination of other
