稀土元素族序数新标法探讨

New Standard Method for REE Group Ordinal Number

分析了通用长式周期表和18列元素周期表的优缺点,探讨了32列元素周期表中稀土元素族序数的新标法及电子构型变化的规律。32列元素周期表既保留了传统周期表把元素按群分类的特点,又符合原子结构的最新研究成果,使每种元素在周期表中只占一格位置,按其分区原则,可以更好地识别各区元素。不仅使用方便,而且利于教学,值得推广应用。

This paper is focused on merit/demerit of the common long- form periodic table and the 18- line elements periodic table. Furthermore, it creatively reorders the rare earth group and discusses the new orderliness of electronic structure changes. 32- line elemems periodic table retains the group - classified elements in traditional periodic table but meets the latest research of atomic structures - each element stands one grid position for better differentiation. It is particularly convenient to be used in teaching.
