徐光宪原子核外电子排布近似规律及其应用

XU Guang-Xian’s Approximate Rule of Electronic Configuration and Its Application

徐光宪根据光谱实验数据对基态多电子原子轨道的能级高低提出了一种理论依据,即中性基态多电子原子核外电子排布近似规律n＋0.7l公式和离子基态多电子原子核外电子排布近似规律n＋0.4l公式。该规律以数学表达式给出,便于推导,较好地解决了难于正确书写原子核外电子构型的问题。对这2个公式的探讨和运用,一方面有利于加深对核外电子组态构造原理的认识,另一方面有助于对我国科学家研究成果的传承。

According to the spectrum experiment data,XU Guang-Xian proposed a theoretical basis for orbital energy level of ground state multi-electron atom,including the approximate rule：n＋0.7l formula for the electronic configuration of neutral ground state multi-electron atoms and n＋0.4l formula for the electronic configuration of ground state multi-electron ions.This rule given in mathematical expressions was very easy to be derived and solved the problem that the electronic configuration was difficult to be written correctly.The discussion and application of the two formulas could deepen the understanding of structure principles of electronic configuration and inherit research results of Chinese scientists.
