When you introduce excess charge into an insulator the charge stays still. Why is this?
When you add charge to an insulator the electrons stay in the same place whereas in a conductor they spread apart. Why is this? What force is making the excess charge stay in one place in an insulator?...

Why are non-metallic elements with partially filled valence bands not conductors?
Throughout this whole question, I will be referring solely to single element solids. According to band theory, ns and np bands are close enough in energy to overlap and create one band with 8N states ...

Can a conductor be uniformly charged?
I have been reading in books that charges on a conductor resides on its surface and that for a body to be uniformly charged it has to be an insulator.Is it true?If yes does it mean we can consider a ...

What makes electrons 'more free or less free' to move around?
I understand that conductors allow electron flow because their valence electrons are 'free' to move around.. But what exactly determines this 'freeness' and the lack thereof that separates conductors ...

Why do we get electric shocks when most structures are insulators?
Suppose I was standing in the sea, and touched an electric fence; I would receive an electric shock, because both my body and the sea are conductors, and create a path for the electricity to flow. The ...
