SUMMARY
Hydrogen cyanide (HCN) has a single resonance structure characterized by a hydrogen atom bonded to a carbon atom, which is triple-bonded to a nitrogen atom. The discussion clarifies that resonance structures involve the movement of electrons rather than atoms, and emphasizes that not all resonance structures must have balanced charges. The most stable structure is typically chosen for representation, confirming that HCN does not exhibit multiple resonance forms.
