组成化合物元素的原子序数关系的确定,是各种考试中较为常见的考查题型。有些同学在处理此类问题时,常常会出现漏选的情况,究其原因有两种情形:一是对物质结构的基础知识掌握的不够扎实,缺乏解题应有的知识基础和基本技能;二是逻辑思维能力较差,分析推断能力不强。下面通过举例分析,希望能够对同学们有所启迪。一有确定的原子数目组成的化合物中原子序数关系的确定 Determination of the relationship between the composition of the atomic number of the elements of the exam is more common in a variety of exam questions. Some students often deal with such problems when there are missed cases. There are two reasons for this: one is the lack of a solid understanding of the basic knowledge of the material structure and the lack of a knowledge base and basic skills necessary to solve problems; Second, poor ability to think logically, analytical ability to infer is not strong. The following examples by analysis, hoping to have some inspiration to the students. The determination of the relationship between atomic numbers in a compound of a defined atomic number
