金属半径和阳离子半径与电子构型的定量关系

元素的金属半径和阳离子半径与其电子构型密切相关 .在周期表中金属半径可以用一个统一的公式计算出来 ,该公式说明金属半径完全可以从元素的电子构型分析计算 ;而通过定性和定量结合的方法则可以揭示出阳离子半径与电子构型的理论联系 .计算结果与文献公布的数值符合较好 ,标准偏差图也说明了计算结果的准确性 .本研究说明金属半径和阳离子半径本质上是元素电子构型的反映 ,是元素在周期表中位置的一种反映     

The quantitative relationship between metal radii, cationic radii and electronic configurations of elements

A close relationship has been found between the metal radii, cationic radii and electronic configurations of elements. A unified formula for calculating metal radii is presented, whose paramatem are only related to the electronic configuration. Meanwhile theoretical relation between cationic radii and electronic configuration can be revealed by combining quantitative analysis with qualitative analysis. The calculated results and the charts of standard deviations are coincident with those given by reference books. Our work indicates that the metal radius and cationic radius of an element reflect in essence the element's configuration.
