Draw the Lewis structures and determine which of these molecules has a central atom that unavoidably violates the octet rule. Please note that NO3 has an odd number of electrons. But you must decide where the missing electron will be. Does the central atom violate the octet rule or do the oxygen atoms? Use formal charges to decide. SO3 BCl3 SO2 NO3- PCl3 NH3 CS2 XeF2 IF5
