摘要: 电负性是化学中的一个重要概念，在基础化学课程中起着关键作用。本文将电负性研究过程分为三个阶段，简述了关于电负性标度的认识不断深入、逐步发展的过程，在讨论不同电负性标度的基础上，着重讨论了绝对电负性标度和Pauling类型电负性标度的差别性、Allen电负性标度及其修正的Rahm标度等，对深刻理解电负性标度这一基本概念及促进无机化学教学内容的改革均有重要意义。

Abstract: Electronegativity has been one of the most important concepts in chemistry. It plays a critical role in fundamental chemistry courses. This paper proposed a view of three periods on the development of electronegativity. The process of deepening and gradually developing in understanding of electronegativity scale is briefly described. On the basis of a brief description of different electronegativity scales, the difference between absolute electronegativity scale, Pauling type electronegativity scale, Allen electronegativity scale and its modified Rahm electronegativity scale were discussed emphatically. The re-discussion is undoubtedly helpful for the in-depth understanding about the concept of electronegativity and the reform of teaching contents in fundamental studies.
