摘　　要：1932年Pauling在研究键能时,首次提出了电负性概念,用其作为原子在分子中对成键电子吸引能力的量度。自Pauling提出后,又出现了Mulliken电负性,Allred和Rochow电负性,Allen电负性等。本文介绍了上述几种电负性并作了简单比较,同时简介了电负性的应用情况。In 1932,Pauling proposed the concept of electronegativity for the first time as a measurement of the ability of atoms to attract bonding electrons in molecules,when he studied key enenrgy. After Pauling＇s proposal,Mulliken electronnegativity,Allred and Rochow electronegativity,Allen electronegativity and so on appeared. This article introduced and made a simple comparison about these electronegativity above. At the same time,the paper introduced the application of electrongativity.
