AP Chemistry
2.3 Structure of Ionic Solids
A student investigates the lattice energies of four crystalline potassium halide salts: \(\text{KF}\), \(\text{KCl}\), \(\text{KBr}\), and \(\text{KI}\). All four salts crystallize in the same cubic lattice geometry, with each compound consisting of \(+1\) and \(-1\) ions. Which of the following lists the potassium halide salts in order of decreasing magnitude of lattice energy, with the correct justification?
