  1. Crystalline Solids

  2. p. 459

  3. Macroscopic structure depends upon microscopic structure.

  4. Pyrite (FeS2, fool’s gold) Fluorite (CaF2) Amethyst (SiO2) – quartz + Fe & Mn

  5. Crystal terms • Crystal – • Lattice – • Unit cell – • Edge length (do) – face edge corner

  6. Packing in Crystals • Atoms and ions are represented by spheres. • The spheres stack in different patterns three-dimensionally. • The close packing of spheres maximizes intermolecular force. • The patterns of stacking result in different types of unit cells and lattices.

  7. Lattice – unit cell relationship

  8. Close packing

  9. Close packing unit cell types

  10. Alloys Intermetallic Compounds

  11. What about the lattice space left over?

  12. NaCl
