Abstract The teaching of “element periodic law” in the selective compulsory stage is carried out with the hot spot of scientific research “hydrogen storage materials” as the carrier. Using the existing “systematic cognitive model of elements and substances” in the compulsory stage, through the two teaching links of selecting elements to prepare metal hydride and analyzing aminoborane, we can understand ionization energy and electronegativity based on cognitive needs, understand double hydrogen bonds, and integrate the new cognition with the existing cognitive model to realize the advancement of cognitive model and the development of systematic thinking ability, cultivate a sense of social responsibility.
