目前大中院校的化学课本都趋向于在讲授原子结构之后,接着讲授元素周期表,这是符合人类对自然认识的规律的。实践也证明,原子结构与周期系统是密切联系着的。根据现代的原子结构理论,所有原子核外围绕着若干层各类型的电子,而每一新层次的出现,都以一定的规律建立各种类型的电子。而且每一同类型电子的重现,元素性质就呈现一定的相似性。
At present, chemistry textbooks in colleges and universities tend to teach the atomic structure and then teach the periodic table, which is consistent with the laws of human understanding of nature. Practice also proves that the atomic structure and the periodic system are closely linked. According to the modern theory of atomic structure, all the nuclei are surrounded by several layers of various types of electrons, and each new layer of electrons is established with a certain regular pattern of various types of electrons. And with the same type of electronic reproduction, the elemental nature presents a certain degree of similarity.
