Taking “the Structure and Properties of N2 Molecule” as an Example to Discuss the Design of Classroom Teaching of Elementary Chemistry
Abstract:
Taking "the structure and properties of N2 molecule" as an example, this paper illustrates the concrete methods in the classroom teaching of elementary chemistry, including closely correlating the molecular structure of nitrogen gas to its chemical properties, introducing the chemical principles involved in photochemical pollution, industrial synthetic ammonia and other practical problems raised in industrial production and normal life, and guiding students to present the reviews in the topics on nitrogen fixation and nitrogen activation.
