B Do Electrons Completely Leave a Capacitor at T/4 in an LC Circuit?

[Antoha1]

Hello. My question is:
When a capacitor in LC circuit is out of charge (T/4) does that mean that all electrons left the capacitor or that there is the same quantity of electrons on both plates?

What do you think?

What would it mean if all the electrons left a block of some material?

Think of this like the more familiar battery. The battery has to be in a circuit (red and black leads) to charge it. The answer to your question is along the same lines.
