Question

Quizplus · Accepted Answer

Li (Lithium) and Cl (Chlorine) are further apart in the periodic table compared to the other pairs, with Lithium being a Group 1 metal and Chlorine a Group 17 nonmetal. Electronegativity increases across a period and decreases down a group, making the difference between Li and Cl larger than the others.
