1) Draw representations of both ionic solids in each set that show the relative differences in the sizes of the four ions, the ratio of cations to anions, and the

charge on each ion; identify which ionic solid will have the higher melting

temperature; and justify your answer. (Formula units that contain two ions must

be drawn as networks consisting of twelve ions in total. Formula units that

contain more than two ions can be represented as a single formula unit.)

a. NaCl or KBr

b. NaCl or MgS

c. BeF, or Lif

d. CaO or CaCl2

e. Mgo or A103
