元素的电负性和它的价态直接有关,这一点首先为Sanderson所认识。后来,Haissinsky应用鲍林(Pauling)的热化学方法计算了部分变价元素在某些价态的电负性,发现电负性随着原子价数的增加而增加。然而Haissinsky关于相同原子间的正常共价键能(M—M)在M变价时保持不变的假设是非常成问题的,因而他的结果值得怀疑。Gordy、高孝恢、袁汉 The electronegativity of an element is directly related to its valence, which is first recognized by Sanderson. Later, Haissinsky applied Pauling’s thermochemical method to calculate the electronegativity of some of the valence elements in some valence states and found that the electronegativity increased with the increase of the valence number. However, Haissinsky’s assumption that the normal covalent bond energy (M-M) between identical atoms remains constant when M is changed in price is very problematic and his results are therefore questionable.
