7) On a separate sheet of paper, use circles to draw a picture of the ionic solids listed
below, being careful to indicate the sizes of the ions relative to one another in each
compound and the ratio of cations to anions in each compound (Ex. MgCl2 has one
cation and two anions per unit, and the Cl ion should be larger than the Mg+2 ion). F
compounds in which the cation: anion ratio is 1:1, draw several formula units in a latt
When the ratio is not 1:1, you may draw just one unit.
Finally, identify which compound will have the higher melting point and justify each
answer, using Coulomb's Law.
a) NaCl or KBr
b) NaCl or MgS
c) BeO or LiF
d) GaP or AIN
