Question

In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the attractive force holding those ions together) Based on ion size, rank these compounds of their expected lattice energy Nal, NaBr, NaCl, NaF Sapling Learning In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the attractive force holding those ions together).

Explanation / Answer

Smallest atomic size means the largest lattice energy.

So, Fluorine has the smallest size, so NaF will have the largest lattice energy, then Chlorine so NaCl will have second largest.Iodine is the biggest ion, so NaI will have the least energy.so decreasing order will be

NaF > NaCl>NaBr > NaI
