Like metallic crystals, ceramic crystals can have defects. We want to identify the type of defects and consider how they affect the overall crystal. Consider the schematic (on the right) of a NaCl crystal after the formation of an Na* vacancy to analyze for lonic type defects: CH Na CI- Na CI- Nat CH CI 7. What is the charge on the crystal before the vacancy is formed? <0.5 mark> 8. What is the charge on the crystal after the vacancy is formed? <0.5 mark> Nat CI Nat 9. What should the charge on an ionic crystal be? Hint: what has the lowest energy; something that is positively charged, negatively charged or neutral? <0.5 mark> 10. Describe a possible way to change the crystal shown (in schematic above) so that the charge on the crystal matches to your answer in question # 9. <1 mark> Like metallic crystals, ceramic crystals can have defects.
