Electronegativity ⅰ . The Effective Nuclear Charge Number Method of Establishing the Elemental Electronegativity Scale

931年在哥伦比亚大学，哈罗德尤里发现同位素，有两个核电荷数。

In1931 , at Columbia University , Harold Yuri discovered this isotope , which has two .

根据类氢离子电离能的实验值和相邻元素电离能的相关约束方程，定量地建立了各元素类氢离子电离能与核电荷数的较为精确的递推关系。

The strict relation of the ionization energies of adjacent hydrogen-like ions with number of nuclear charges is set up based on the experimental values of the ionization energies .

两个反应系统虽然具有相同的核电荷数，但轻粒子He和中等质量碎片在多重性中的比分有明显的同位旋相关性。

The experimental results of these two reaction systems with the same nuclear charge indicate that the contributions of He and IMFs in the total charged particle multiplicities are obviously isospin dependent .

发现此关系式与主量子数和角量子数有关，而与核电荷数以及折合质量无关。

It is pointed out that the relation has something to do with the principal quantum number and the angular quantum number , but nothing to do with the nuclear electronic number and reduced mass .

通过价层电离能、价键轨道能量用有效核电荷数法建立了周期表中90种元素的电负性新标度。

Through the ionization energy of the valence shell and the energy of the valence bond orbital , the new scale of the electronegativity of 90 elements in the Periodic Table has been established by the effective nuclear ~ charge number method .
