Delocalization of Electrons

[Neel Bonthala 2G]

So to my understanding, in resonance structures, electrons that form double bonds are delocalized because they exist in multiple locations (equivalent electron density). But does this mean electrons involved in single bonding and lone pairs are not delocalized? Or are they also equally shared among all atoms in the molecule?

I'm pretty sure that the electrons within a system that are not resonant and have localized electrons.

Furthermore, localization has to do with the electrons being on the internuclear axis, not necessarily a set location I believe.

"Double bonds" electrons are off axis and are not on the internuclear axis, and hence is considered delocalized.

Hope this helps!

For non-resonance structures, electrons are localized.
