在“原子电子层结构和周期系”的教学中,国内外教科书多采用各种形式的aufbau(构造)图(见3—6图)来帮助学生了解核外电子的填充顺序。所谓 aufbau 图,也就是电子填入“轨道”次序图。由于原子核外电子的填充次序与元素周期系的形成有内在联系,故进一步引伸和改进已有的电子填入“轨道”次序图的含义和应用,是很有必要的。本文提出的“能级组式电子填入‘轨道’次序图”,是在教学实践和文献的启 In the teaching of atomic electron layer structure and period system, the domestic and foreign textbooks mostly adopt various forms of aufbau diagrams (see Figure 3-6) to help students understand the filling order of extranuclear electrons. The so-called aufbau diagram, which is electronically filled in the “orbit” sequence diagram. It is necessary to further extend and improve the meaning and application of the existing electron-filled “orbit” sequence diagrams because the filling order of extranuclear electrons is intrinsically linked to the formation of periodic elements. This paper presents the “level group electronic fill track orbit sequence diagram” is in the teaching practice and literature Kai
