摘要
选用化学元素的密度、半径、燃烧焓、熔点、沸点、电负性及导热系数 7个理化参数 ,运用系统模糊聚类分析方法 ,对化学元素周期表中的 50个元素进行了分类。分类结果大多与传统周期表匹配 ,但也表现出按外层电子结构排布规律所不能解释的现象 ,如锰为独立一组 ;Be、Si、AI为一组 ,Si具有较明显的金属性等。
The systematic fuzzy cluster analysis was applied to chemical periodic table for the elementary rearrangement. Seven properties, i.e. density, diameter, enthalpy, melting-point, boiling-point, electronegativity, and thermal conductivity, were adopted for the cluster analysis. An interesting fact is that Mn has been isolated from the former 50 elements of the periodic table. Be, Si, Al, and Sr were slightly different from the table. This software was compiled in VC++ 5.0 under Windows 95.
