Shortly after Bronsted and Lowry proposed their definition of acids and bases, the American chemist Gilbert Newton Lewis, building upon his new understanding of the nature of the chemical bond, proposed the definition that an acid is an electron pair acceptor while a base is an electron pair donor. This definition is more general than the Bronsted-Lowry definition and builds upon earlier work by Lewis that the electron pair is the major instrument of bond formation. A simple reaction that illustrates this new definition is the reaction of a proton with a hydride ion. The proton, due to its positive charge and the absence of electrons around the proton, is capable of accepting a pair of electron. The hydride ion has two electrons a lone pair, or non bonded pair and can therefore donate these two electrons to the proton.
