Question

Resonance structures differ by ________. resonance structures differ by ________. number of atoms only number of electrons only number and placement of electrons placement of electrons only placement of atoms only

Answer 1

The answer to this question would be: placement of electrons only

An atom with resonance structure or mesomerism has one or more different structure with different placement of the electron. The atom should have a same amount of electron but only differ in the electron position. This will result in a different Lewis structure model. In this structure, you can find π electrons pair.
