Part A - Resonance Structures Which of these statements about resonance is true? When you draw resonance structures, it is permissible to alter the way atoms are connected. O The cyanide ion has only one dominant resonance structure. O The nitrate ion has one long N-O bond and two short N-O bonds. O"Resonance" refers to the idea that molecules are resonating rapidly between different bonding patterns. O All of the above are true. Submit Request Answer rovide Feedback
