Why when a chemical species is stablized by resonance, its energy

Click For Summary
SUMMARY

The discussion clarifies that resonance stabilization in chemical species leads to a lower energy level due to electron delocalization. This delocalization results in a more even distribution of charge, which decreases electrostatic repulsion among like charges and enhances attraction between opposite charges. The participants agree that this stabilization occurs independently of environmental interactions, reinforcing the concept that resonance directly contributes to energy reduction in molecular structures.

Why when a chemical species is stablized by resonance, its energy level is lower? As I know, resonance is only a kind of electrons delocalization within the species. There is no interaction between that species and the environment.

Stabilization is equivalent to lowering the energy. Conceptually, you can think of the charge being more evenly distributed when the electrons are delocalized---thus decreasing the electrostatic repulsion between like-charges, and better saturating between opposite charges (i.e. nuclei and electrons).
These processes don't require any interaction with the environment.
