Chemists have successfully synthesized the ionic compound [N₅][SbF₆], which consists of N₅⁺ and SbF₆^–  ions. Draw Lewis structures for these ions and assign formal charges to the atoms in your structures. Describe the structures of these ions. [Hint: The skeleton structure for N₅⁺ is N—N—N—N—N and several resonance structures can be drawn.
