惰性电子对效应的教学思考

Teaching Thinking Based on the Inert Electron Pair Effect

原子核外电子分布的周期性是元素周期律的基础,元素周期表是元素周期律的表现形式。随着对元素及其化合物性质的深入研究,表明元素周期性并不是简单的重复。在教学过程中,首先引入惰性电子对效应这一周期反常现象,探讨其产生原因并加以总结。在此过程中培养了学生提出问题、分析问题、解决问题的能力,使其综合归纳能力得以提高,有利于学生形成辩证唯物主义世界观。

The periodicity of electron distribution outside the nucleus is the basis of the periodic law of the elements,and the periodic table is the manifestation of the periodic law of the elements.With the in-depth study of the properties of the elements and their compounds,it has been shown that the periodicity of the elements is not a simple repetition.In the teaching process,first introduce the periodic anomaly phenomenon of the inert electron pair effect,explore its causes and summarize them.In this process,the students′ability to ask questions,analyze problems,and solve problems is cultivated,and the ability of comprehensive induction is improved,it also helps students to form a dialectical materialist world outlook.
