Examine the trends in lattice energy in Table 12.1. The value of the lattice energy becomes somewhat
Question:
Examine the trends in lattice energy in Table 12.1. The value of the lattice energy becomes somewhat more negative on going from NaI to NaBr to NaCl, and all are in the range from −700 to −800 kJ/mol. Suggest a reason for the observation that the lattice energy of NaF (ΔlatticeU = −926 kJ/mol) is much more negative than those of the other sodium halides.
Data given in Table 12.1
