对于元素化合物的性质,许多同学反映知识零碎,没有规律,难以记忆和掌握。其实,我们只要能够从“通性”和“特性”两个角度来认识物质的性质,采用“类别→通性→特性”的学习模式,对元素化合物的性质进行总结,就会取得事半功倍的效果。所谓通性,就 For the nature of the elemental compounds, many students reflect the fragmentary nature of the knowledge, lacking regularity, and having difficulty remembering and mastery. In fact, as long as we can understand the nature of matter from the perspectives of “generality ” and “characteristic ”, we summarize the properties of the elemental compounds by adopting the learning mode of “category → generality → characteristic” It will achieve a multiplier effect. The so-called generality, it
