Question 61 [6 marks] (a) In the crystal structure of sphalerite (ZnS), the sulfur anions (S2) adopt a face-centred cubic arrangement. Using the cubic framework shown below, draw the anion locations in a face-centred cubic unit cell. (Represent each ion as a small solid circle). For the face-centred cubic unit cell you have drawn in (a), how many sulfur anions (b) make a contribution to the unit cell? What is the sulfur anion content of the face-centred cubic unit cell...

Answer question 23-25 The unit cell for HCP is not a cube. This structure is made by placing one flat layer of a close packed hexagon arrangement of seven spheres on top of the holes in another layer, a third layer directly above first layer, and so on. This layering is referred to as A,B,A,B. Hold the model up to the light and note the tunnels that pass straight through the structure. See the figure below. 23. What is the...
