Electronegativity from Avogadro to Pauling: II. Late Nineteenth- and Early Twentieth-Century Developments

Abstract
Part I of this three-part series traced the origins of the electronegativity concept in the work of Avogadro and Berzelius in the period 1809-1813. Part II traces the manner in which the electronegativity concept, after its initial eclipse in the period 1840-1869, was reconciled with the newer concepts of valence and chemical structure that resulted from the second chemical revolution of 1855-1875. In particular, this paper traces the accommodation process as it occurred in four fundamental areas of chemistry in the period 1870-1910: the relationship between electronegativity and classical valence, the relationship between electronegativity and the periodic law, the relationship between electronegativity and thermochemistry, and the relationship between electronegativity and the newly emerging electrical theory of matter.
