从电子能级分组和排布的经验规则谈起

COMMENTS ON THE EMPIRICAL RULE OF THE GROUPING OF ENERGY LEVEL AND ELECTRONIC CONFIGURATION

许多教科书把n+0.71等经验规则作为判断原子(外层)轨道能级高低次序的依据,而且对电子排布的根本原则——能量最低原理的表述不正确,造成在多电子原子核外电子排布问题上的概念混乱,本文对此作了必要的讨论。

In many textbooks, the empirical rule of (n+0.71) has been presented as a means for determining the order of energy levels of outer layer atomic orbits, furthermore, misleading description on the basic principle of electronic configurations in atoms (the principle of the lowest energy) are found in these books, confusion has thus been created in regard to the electronic configuration outside of the nucleus of a multi-electron atom system. Comments in this respect are presented in this paper.
