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
