Unformatted text preview: for the ionic solids that are made of ions with low charge (giving low lattice energy). It turns out that in this problem all of the ions involved have a +1 or -1 charge, so we must next consider size. If the ions in an ionic species are small, then they can get closer to one another giving a stronger attraction. We should therefore look for the ionic solid that is made of the largest ions, because we are looking for compound with the least amount of lattice energy. Potassium iodide has the two largest ions and would thus be easiest to pull apart, or in other words, have the smallest lattice energy....
