巧用物理力学解决化学教学中分子极性的理解难题

Using mechanical knowledge in Physics to explain the polarity of the molecular in Chemistry teaching

文章运用物理学科中简单的共点力的合力的知识结合化学分子构型,将抽象的共价键的极性用实际直观的作用力来代替,很好的解决中学化学教学中关于共价健的极性和分子的极性的化学概念的教学和理解问题,通过实例说明了该种方法的思路和优点,为当前中学教学与学习中注重学科之间的相互交叉与渗透做出了初步的尝试。

The author replaced the abstract covalent bond polarity with the visual force using the simple knowledge of the total points force in physics together with the structure of chemical Molecular, It＇s a good Method to explain the chemical concept on the polarity of the covalent bond and molecular. In the paper plenty of examples were listed to state the ideas and merits of this mean. It＇s a preliminary attempt to pay attention to the crossover and infiltration Between disciplines In the course of the current secondary school teaching and learning.
