B) P < Cl < F

D) P < F < Cl
E) Cl < F < P

Quizplus · Accepted Answer

Electronegativity increases across a period from left to right and decreases down a group in the periodic table. Since phosphorus (P) is to the left of chlorine (Cl) and fluorine (F) in the same period, and fluorine is the most electronegative element, the correct order is P < Cl < F.
