<正> 一、引言量子力学对氢原子处理得到满意的结果,不仅得到的能阶符合实验结果,并且所得的轨函亦可用来对周期表各元素作一大致的描述。对于多电子原子模型,量子化学尚无严恪的数学处理方法,虽然在应用近似处理方法上不断有所改进,使结果更加逼近,但由于元素及化合物的许多性质只决定于最外层电子(或次外层电子),它们微少的电离势差别及轨函改变就可导致性质的大幅度变化。用目前的多电子原子模型的近似处理法,还无
Abstract：It is recognized in this paper that the screening contants of electrons for the neighbowing outer electronic shell are changed and become larger and smaller alternately, ie, the successive electronic shells are situated in loose and tight state alternately relative to the ideal standard state. This phenomena is called "The alternation effect of loosenese and tightness". After considering in the meantime the other two screening effect of electrons (S2 screening effect and d10 screening effect), the authors have found a alternation rule of looseness and tightress for the atomic model, and have discussed its presentation on ionization potentials, covalent radius, ionic radius and electronegativity of elements, as well as the application of this sule to explain many important propesties of the elements and compounds in the periodie table
