Problem: Draw the Lewis structure for the trisulfur (S 3) molecule. Be sure to include all resonance structures that satisfy the octet rule.

We are being asked to identify the resonance forms of S₃. 

First, we will have to draw the Lewis Structure of S₃.

Step 1: Determine the central atom in this molecule.

• There is only 1 atom in the structure → Sulfur is the central atom

Step 2: Calculate the total number of valence electrons present.          

S₃:

           Group              Valence Electrons

S         6A                    6 valence e^- x 3
                                    Total = 18 valence e^-
