The application of quantum mechanical processes to the theory of metals has led to a spectacular resolution of certain basic disparities between theory and experiment. In this work the authors use quantum methods to develop mathematical models which account for the properties of pure metals and alloys. In particular, they show how crystal structure, magnetic susceptibility, electrical and optical properties, and fundamental chemical phenomena are related. Experimental results are linked closely with theory and where more than one formulation has been proposed the merits and drawbacks of each are discussed.
