Ionic Bonding

Here we introduce the concept of ionic bonding, including electronegativity, the Madelung constant, lattice energy, the Born Haber cycle, and Pauling’s Rules. The chapter ends with the empirical application of Fajans’s Rules to estimate the ionic fraction of bonds and a comparison between ionic and covalent bond strengths. Brief biographies of Erwin Madelung, Max Born, and Linus Pauling are also included.
