A cation vacancy paired with an anion vacancy is called Schottky defect. The Frenkel defect is an ion vacancy and a corresponding ion interstitial impurity. Other types of defects can exist. One particular type involves multiple Fe Fe Fe Fe oxidation states. Transiton metal atoms, such as iron, can have more than one oxidation state or charge. For example iron can exist as Fe*, Fe*, or Fe*. If the oxidation state of an ion in a crystal changes, that is another type of defect. The figure below shows a crystal of FeO after one of these defects is formed. One of the iron atoms has been oxidized to a charge of +3 instead of the normal +2. You will use charge Fe Fe balance to determine the defects that form when the oxidation state of one atom is changed. Keeping this in mind answer the following with respect to the figure below: 11. What is the charge on the crystal before the defect is formed. 12. What is the charge on the crystal after the defect is formed. 13. What is one thing you…
