Many sources define lattice energies as negative values. Please rank by magnitude and ignore the sign. Lattice energM absolute value of the lattioe energy AO Previous 8 Give Up & Mew Solution 2 Check Answer Not H Ext

Explanation / Answer

For a given cation, as the size of anoin decreases the ionic nature increases. Hence the lattice enrgy.

So, NaF > NaCl > NaBr > NaI

Size of decreases in the order, I- > Br- > Cl- > F-

Smaller the anion higher is the lattice energy.
