Copper salts – Assume that, in this question, thecation-to-anion size ratio should be in the 0.25 – 1 range and thatall compounds adopt cubic cells. a) The chloride atoms are intetrahedral holes in copper(I) chloride (Copper has +1 charge).Draw the unit cell of copper(I) chloride. b) Propose a unit cellfor copper(II) chloride (Copper has +2 charge) and draw. c)Determine the coordination numbers for copper and chloride atoms incopper(II) chloride. d) Compare the densities of copper(I) chlorideand copper(II) chloride. e) Compare the lattice parameters forcopper(I) chloride and copper(II) chloride. f) Propose a unit cellfor copper(I) sulfide (Copper has +1 charge) and draw. g) Determinethe coordination numbers for copper and sulfide atoms in copper(I)sulfide.
