在教电子构型一节时,学生们往往感到难于记住轨道的填充次序,许多教科书(也有不少教师)对此也没有给出有效的解决办法。本文介绍一个简便实用的方法,将有助于对这一问题的学习和记忆。做法如下: 1.画一张7×7的方格子图。 2.在对角线上算出已知的各S轨道。如图
When teaching the electronic configuration section, students often find it difficult to remember the order of filling the tracks. Many textbooks (and many teachers) do not give effective solutions. This article describes a simple and practical method that will help in learning and remembering this problem. Here’s how: 1. Draw a 7×7 square grid. 2. Calculate the known S orbits on the diagonal.
