Which of the following ranks the compounds from lowest to highest lattice energy? A) NaF

Question

Which of the following ranks the compounds from lowest to highest lattice energy? A) NaF < MgF₂ < CaF₂ < KF B) KF < NaF < CaF₂ < MgF₂ C) MgF₂ < CaF₂ < NaF < KF D) CaF₂ < KF < NaF < MgF₂ E) MgF₂ < CaF₂ < KF < NaF

Quizplus · Accepted Answer

Lattice energy increases with higher charges and smaller ionic radii. MgF₂ has the highest lattice energy due to the +2 charge on Mg²⁺. NaF and KF have lower lattice energies, with KF being the lowest due to the larger size of K⁺.
