Lewis Structures and Amphoteric Compounds

How can you tell if a compound is amphoteric based on its Lewis structure?

I think one of the ways that could be a good signifier is if there is an unbalanced dipole moment in the Lewis structure. For example, water is an amphoteric compound with a negative dipole on the oxygen and a positive dipole on the hydrogen side. That is why it can act as an acid and give off a hydrogen to a base or act as a base and accept a hydrogen (because of the electrostatic attraction between the H+ and the oxygen atom in water) from an acid
