SO2 Step 6
Picture so Far:
Notice that both these structures are valid Lewis structures.
This process is called resonance and means that the actual molecule has
two equivalent bonds between the sulfur and the two oxygens. Both
S-O bonds are the same length--a little shorter than a single bond, but
not as short as a double bond.
