自从电负性概念被提出以来,已经超过半个世纪了。现在它已成为化学科学中应用最广的概念之一,不少人对这个问题作过综述。然而六十年代之后,随着量子化学的发展,有关电负性的理论和应用方面都取得了不少成就。在国外是一个重新引起兴趣的课题,所以有必要就这个问题近代发展的主要方面予以综述。 It has been more than half a century since the concept of electronegativity was proposed. Now it has become one of the most widely used concepts in chemical science, many people reviewed this issue. However, since the 1960s, with the development of quantum chemistry, many achievements have been made in the theory and application of electronegativity. It is a topic of renewed interest in foreign countries. Therefore, it is necessary to review the major aspects of the modern development of this issue.
