Q1:An interstitial alloy prepared from two metals. metal A with the larger atomic radius has a hexagonal closed-packed structure. What if the formula(for example:A2B,AB,AB2)of the alloy if atoms of metal B occupy the following?

All of the tetrahedral holes ......

One -half of the tetrahedral holes.......

One-half of the octahedral holes......

Q2:A number of metal fluorides adopt the fluorite structure in which the fluorite ions occupy all the tetrahedral holes in a face-centered cubic arry of metal ions. For at least one(maybe more) of the highlighted metallic elements in the figure, this crystal structure should not be possible. Which one(s)?

Q3:Calculate the density of CsCl? (CsCl described as body-centered cubic, 412pm)
