With your 12 electron valence case you must also include the prerequisite for that: having electrons in d-orbitals of sulfur; which has been disproved quite a few times. (Expanded octett, hypervalency to name the trigger words.) Plus it is absolutely unnecessary to describe bonding in that way, as is resonance, and the combination of …

Explanation: 5 steps: 1) Find total number of valence: P = 5 and Cl3 = 21; T ot = 26. 2) Always the most electronegative element in the middle: P. 3) Use two electron to form a bond. 4) Complete the octet on the outside atom. 5) If are not able to complete Octets move to the inside to form a double or triple bond.
