纵观近几年高考试题,选修模块3的考查热点包括电子排布式、电离能、分子的空间构型、中心原子的杂化类型、晶体结构计算等.现结合2013年高考试题,对常见易错点进行剖析,并对解题技巧进行归纳.1电子排布式考试说明中要求了解原子核外电子的能级分布,能用电子排布式表示常见元素(1～36号)原子核外电子的排布.
Looking at the examination questions in recent years, the examination hot spots of elective module 3 include electronic arrangement, ionization energy, spatial configuration of molecules, hybrid types of central atoms, crystal structure calculations, etc. Now combined with 2013 exam questions, common Error-prone points are analyzed, and problem-solving techniques are summarized. 1 The electronic arrangement test description requires knowledge of the energy level distribution of the electrons outside the atomic nucleus, and the electronic elements can be used to represent common elements (No. 1 to No. 36). The arrangement.
