Item 8 Part A CI The lattice energies of NaCl and KF are given in the table in the introduction. Based on the lattice energies, would you expect the Na or the K - F distance to be longer? NaCl and KF have the same crystal structure. The only difference between the two is the distance that separates cations and anions. Match the words in the left column to the appropriate blanks in the sentences on the right. Lattice Lattice Reset Help Compound Energy Compound Energy kJ/mol 1030 834 730 910 k.
