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.)
NaCl or KBT
NaCl or MgS
BeF2 or LiF
CaO or CaCl2
MgO or Al2O3
