MgO has a structure of NaCl and TiCl has the structure of CsCl. What are the coordination number of ions in each (MgO and TiCl)

a. MgO has the structure of NaCl and TICI has the structure of CsCl . What are the coordiantion number of the ions in MgO and TICI ? If the closed-packed cations in an XY -type solid have a raidus of 73.2 pm, what would be the maximum and minimum sizes of the anions filling voids? c. Fe_(2)O_(3) (haematite) forms ccp arrangement of O^(2-) ions with Fe_(3+) ions occupying initerstitial positions. Predict whether fe^(3+) ions are in the OV or TV . Given r_(Fe^(3+)) = 0.7 Å and r_(O^(2-)) = 1.4 Å d. A solid XY has CsCl -type structure. The edge length of the unit cell is 400 pm Calculate the distance of closest approach between X^(o+) and Y^(ɵ) ions.
