CHEMISTRY 121 1 Department of Chemistry University of British Columbia Problem Set 12 Solids *Some of the questions on this problem set deal with laboratory Experiment #7 which is not discussed in lecture. 1. (a) MgO crystallizes in the rocksalt (NaCl) structure. What is the coordination number of the cations in MgO? (b) Sketch the location of all the ions on one face of the unit cell of MgO. 2. A compound containing Ag and O crystallizes as a fcc arrangement of Ag ions with O ions occupying two of the tetrahedral holes. (a) Calculate the empirical formula of the compound. (b) What is the coordination number of Ag in this compound? (c) What is the coordination number of O in this compound? 3. The mineral Spinel can be described as a face-centered cubic arrangement of oxide ions, with one eighth of the tetrahedral holes occupied by magnesium ions, and one half the octahedral holes occupied by aluminum ions.
