在化学学习过程中,要对单质和化合物进行系统学习,才能建立更加有效的化学知识网络,提高问题处理能力,确保对课程内容建构更加完整的处理机制。本文从单质碳元素和硅元素、单质氧气和氯气、氮元素和硫元素以及氮气和一氧化氮、二氧化氮的对比进行综合分析,旨在为学生提供有效的学习技巧,顺利提升化学能力和成绩。 In the process of chemistry learning, we should systematically study the elementary and chemical compounds to establish a more effective chemical knowledge network, improve the problem-solving ability and ensure a more complete processing mechanism for the course content. In this paper, a comprehensive analysis of the carbon and silicon elements, elemental oxygen and chlorine, nitrogen and sulfur, as well as the comparison of nitrogen and nitrogen monoxide, nitrogen dioxide, aims to provide students with effective learning skills, improve the chemical capacity and Score.
