Abstract Based on the scientific definition of the content of “atomic structure”, it is considered reasonable to name the chapter “atom and atomic structure”. The teaching contents should include five modules, namely, the structure and properties of atoms, the establishment and evolution of atomic structure model, the arrangement of extranuclear electrons, the introduction of nuclear structure model, and the relationship between atomic structure and periodic law of elements. The teaching key points for “Bohr atom model, description of the motion state of extranuclear electrons, four quantum numbers, the arrangement of extranuclear electrons, and the relationship between atomic structure and periodic law of elements” have been highlighted in the system. The special lecture on “basic concepts of quantum mechanics” held in advance is conducive to the breakthrough of the teaching difficult point of “quantized atomic structure model”. For each difficult point, the specific methods and measures are also put forward. It is proposed to give lessons by using the philosophical methods of divergent thinking as the main one and convergent thinking as the subsidiary one, doing something and not doing anything, and balance. The purpose is to enable students to acquire basic knowledge and learn some scientific thinking methods, learning methods and research methods after studying this chapter.
