Which of the following requires the smallest energy to separate the ions? A)CaF₂ B)KF C)NaF D)MgF₂ E)LiCl

Question

Quizplus · Accepted Answer

KF has the smallest energy required to separate the ions because potassium (K) is a larger atom with a lower ionization energy than the other cations and fluorine (F) is a smaller atom with a higher electron affinity than the other anions. This results in weaker electrostatic attraction between the ions, leading to a lower energy required for separation.
