摘要：

以"N2分子的结构与性质"为例说明元素化学课堂教学中的具体做法，教师引导学生复习化学键理论解释氮气分子结构与其化学性质之间的关系，组织学生以分组方式讨论光化学污染、工业合成氨等实际生产生活问题中的化学原理，由教师主讲化学模拟固氮的研究思路，而鼓励学生以报告形式展示热化学、电化学等氮活化科研课题的进展情况。

关键词: 元素化学, 课堂教学, 氮气, 合成氨

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.

Key words: Elementary chemistry, Classroom teaching, Nitrogen gas, Ammonia synthesis
