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. IN THE ANSWER THAT YOU GIVE DO NOT DRAW THE STRUCTURE. JUST TELL ME THE ANSWER. EXPLANATION NOT WANTED. NO3- CS2 SO3...
