NaCl has a more exothermic lattice because Na+ and Cl- ions are very strongly ionic and therefore, the lattice energy of NaCl is more than that of CaS
Li2O has a more exothermic lattice because Li+ ion has a smaller ionic radius when compared to Na+ ion, and therefore, the lattice energy of Li2O is more than that of Na2O.
LiF, NaCl ...
Solution explains which compound, in a multitude of pairs of ionic substances, has the most exothermic lattice.
