Writing resonance structures rules for drawing reasonable resonance structures for a given molecule all resonance structures must be valid lewis structures.
Two lewis structures can be written for sulfur dioxide the only difference between these lewis structures is the identity of the oxygen atom to which the double bond is formed as a result, they must be equally satisfactory representations of the molecule interestingly enough, neither of these structures is correct. The lewis structure for each molecule was found and the vsepr model was sketched for molecules that didn't have any lone pairs like ch4,bf3,co2,ch20 and pf5 the angles and shapes were similar in all the models that were used for molecules that contained five different atoms like ch4 and the nh4.
