大家早已知道,一个具有8-电子外壳的金属离子(以下简称惰型金属离子),与一个非惰性气体原子外电子壳结构的金属离子(以下简称非惰型金属离子),尽管它们彼此具有相同的电荷和相近的半径,其所表现的性质(如其盐的点阵能、离子的水合热等)往往相差较大。因此仅用离子的电荷、半径,统一比较它们的性质是困难的。本文提出金属离子的能量半径,尝试应用金属离子的能量半径和电荷,在一定范围内,可以将上述两类离子统一起来比较它们的性质。
It has been known for a long time that a metal ion having an 8-electron shell (hereinafter referred to as an inert metal ion) and a non-noble gas atom having an electron-shell structure (hereinafter referred to as a non-inert metal ion) although they have the same Of the charge and the similar radius, the performance of its properties (such as its salt lattice energy, ion hydration heat, etc.) often differ greatly. Therefore, it is difficult to compare the properties of ions only by their charge and radius. In this paper, we propose the energy radius of metal ions, trying to apply the energy radius and charge of metal ions, in a certain range, these two types of ions can be unified to compare their properties.
