Please help A cation vacancy paired with an anion vacancy is calledSchottky defect. The Frenkel defect is an ion vacancy and acorresponding ion interstitial impurity. Other types ofdefects can exist. One particular type involves multipleoxidation states. Transiton metal atoms, such as iron, canFehave more than one oxidation state or charge. For exampleiron can exist as Fe*, Fe2+, or Fe3+. If the oxidation state of anFeFeion in a crystal changes, that is another type of defect. Thefigure below shows a crystal of FeO after one of these defectsis formed. One of the iron atoms has been oxidized to acharge of +3 instead of the normal +2. You will use chargebalance to determine the defects that form when theoxidation state of one atom is changed. Keeping this in mindanswer 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 could do to the crystal to try to make the charge zero? What is thecharge after you do this?The charge may not be zero at this point; you should just do one thing that starts to getyou in the right direction.14. What is the unit cell of ferrite?15. Describe the unit cell of austenite.16. What change has occurred on going from the austenite form to the martensite form?
