廿多年来许多作者提出各种计算电负性的方法,但所求得的各原子电负性数值,均不尽一致.不幸的是目前尚无法直接由实验测定电负性,很难判断那一种计算方法较为合理.此外,多位作者尚对中性原子的轨道电负性、键的电负性以及自由基的电负性、原子团的电负性进行计算. 上述各种电负性标度大多由能量观点出发,本文建议以原子对其价电子的平均有效吸引力F(r)作为计算原子电负性x的标度,即
Many authors have proposed various methods for calculating the electronegativity over the past 20 years, but the values of the electronegativities of the atoms obtained are not all the same. Unfortunately, it has not been possible to determine the electronegativity directly from the experiment at present and it is difficult to judge A calculation method is more reasonable.In addition, a number of authors still on the neutral atom orbital electronegativity, bond electronegativity and free radical electronegativity, atomic group electronegativity calculation.The above various electronegativity Mostly from the energy point of view of the scale of view, this paper suggests that the atomic valence electron average effective attractive force F (r) as a measure of atomic electronegativity x scale, that is
