Ionic Bonding

A certain form of AgI adopts the zincblende (ZnS & FCC)structure. The density of the salt is 5.69 g/cm3. a) Calculate the length of a side of the unit cell b) Calculate the distance between the Ag+ and the I- ions in the structure.

Ionic Bonding

The alkaline earth oxides MgO and BaO adopt the rock salt (NaCl) structure with cell parameters a of 4.213 à… and 5.139 à…. Using 1.40 à… as the radius for the oxide ion: a) Calculate the radius ratios r(M2+) / r(O2-) for these compounds b) Using the radius ratio rule, indicate whether or not the value found are in agreement with the adoption of the NaCl structure by these compounds. Justify your answer.
