对晶体结构进行分析以确定晶体的化学式是“物质结构与性质”内容中的一个重要考点,要想顺利解决这个问题,就要对常见的晶体类型比较了解,同时需要掌握一定的晶体结构分析方法,下面首先介绍一下几种典型的晶体模型.1.原子晶体(1)金刚石的空间结构是:每个碳与4个碳以共价键结合,形成正四面体结构,键角均为109°28’,最小碳环由6个C组成且六原子不
Analysis of the crystal structure to determine the crystal’s chemical formula is “material structure and nature ” content of an important test site, in order to successfully solve this problem, it is necessary to understand the common types of crystals, at the same time need to master a certain degree of crystal structure Analytical methods, the following first introduce some typical crystal models.Atomic crystal (1) diamond spatial structure is: each carbon and four carbon covalent bond to form a regular tetrahedron structure, the bond angle is 109 ° 28 ’, the smallest carbocycle consists of 6 C and the six atoms do not
