How many resonance structures does NH3 have?
I believe that there are none, but I would like some confirmation...

Question

photon336 · Answer

Do you know what resonance is?

anonymous · Answer

I think that a resonance structure is a visualization of molecular structures, a more comprehensive representation than the Lewis Structure.

Good, another way to explain it is this; 

Resonance shows the movement of pi electrons, remember you can't have resonance in a molecule with only sigma bonds i'll show you these. 

look at this example, is there any resonance in this structure?
