Problem
The ionic radii of selected cations are Li⁺ 76 pm, Na⁺ 102 pm, and K⁺ 138 pm. All three form chlorides with Cl⁻ (181 pm). Which ranking correctly orders the lattice energies of LiCl, NaCl, and KCl from greatest (most negative) to least (least negative)?
(a) KCl>NaCl>LiCl
(b) LiCl>NaCl>KCl
(c) NaCl>LiCl>KCl
(d) LiCl>KCl>NaCl
