Step 1: The total valence electrons of PF4Cl are:


          Group           Valence Electrons

P        5A                1 ×5 e-  = 5 e-

F        7A                4 ×7 e-  = 28 e-

Cl       7A                1 × 7 e- = 7 e-

                               Total: 40 valence e-


Step 2: P (EN = 2.1) is less electronegative than Flourine (EN = 4) and Cl (EN = 3) → P is the central atom
