Homework Ch. 5 2 Introduction to Materials Science 5.3 Calculate the energy for vacancy formation in silver, given that the equilibrium number of vacancies at 800 o C (1073 K) is 3.6x10 23 m -3 . The atomic weight and density (at 800 o C) for silver are, respectively, 107.9 g/mol and 9.5 g/cm 3 . 5.8 Below, atomic radius, crystal structure, electronegativity, and the most common valence are tabulated, for several elements; for those that are nonmetals, only atomic radii are indicated. Which of these elements would you expect to form the following with copper: (a) A substitutional solid solution having complete solubility? (b) A substitutional solid solution of incomplete solubility? (c) An interstitial solid solution?
