浅析元素二次周期性

本文采用以元素二次周期性与元素一次周期性相比较的方法,从原子结构入手对元素二次周期性的特征、产生的原因及定性的理论解释进行了分析。指出在说明元素性质时,不仅要考虑外层电子排布的影响,而且也要考虑内层电子排布的影响。只考虑外层电子的排布仅能得到一次周期性,只有同时考虑外层、内层电子的排布,才能得到二次周期性,乃至三次周期性等。

A Preliminary Analysis of Secondary Periodicity of Element

Based on atomic constructure, the features and origin of secondary periodicity of element are analysed and a theoretical explaination is given in this paper by means of comparison between the first and secondary periodicities of element. It is pointed out that, when the properties of element are to be explained, not only the influence of the arrangement of outer electrons but also that of inner electrons should be considered. Only first periodicity can be obtained when outer electro arrangement is considered alone. Secondary and even third periodicity would have been obtained only if the arrangement of outer and inner electron lagers had been considered multaneously.
