认识分子或原子的结构是高中化学对学生提出的要求。构造原理(随核电荷数递增,大多数元素的电中性基态原子的电子按顺序填入核外电子运动轨道)阐明了核外电子排布的基本规则,许多有关化学键的课题都建立在对电子排布情况的准确认识之上。然而,学生在学习原子理论基础知识的同时,却很少有关于这方面的实验相对应。尽管分子或者原子模型能够帮助学生理解,但远远比不上实验直观。为了解决这个问题,笔者设计了一个能够帮助学生 Understanding the structure of molecules or atoms is what high school chemistry demands of students. The principle of construction (with the increasing number of nuclear charges, the electrons of the neutral ground state atoms of most elements are filled into the orbit of the outer nuclear electrons in order) explains the basic rules of the nuclear electronic arrangement, and many issues related to chemical bonds are established on the basis of Accurate understanding of the electronic arrangement. However, while students learn the basic knowledge of atomic theory, they rarely correspond to experiments in this area. Although the molecular or atomic model can help students understand, it is far less intuitive than experimentation. To solve this problem, the author designed a tool to help students
