Calculate energy for vacancy formation in silver given that the equilibrium number 800 C (1073 K, is 3.6 x 10^22/m^2. The atomic weigh, and density (at 800 C) for silver are. 107.9 g/mol and 9.5 g/cm^2. The following table shows the atomic radius, crystal structure, electronegativity and common valence for several elements; for those that are nonmetals, only atomic radii Which of these elements would you expect to form the following with copper: A substitution solid solution of incomplete solubility? An interstitial solid solution?
