Recall that the trend for atomic radius is as follows: it increases from right to left and down a group in the periodic table.
higher atomic radius → lower lattice energy
Which of the following trends in lattice energy is due to differences in ionic radii?
(a) NaCl > RbBr > CsBr
(b) BaO > KF
(c) SrO > SrCl2
