Why is charge on the surface of a conductor?

Keeping this in view, why there is no charge inside a conductor?
Also, the electric field inside a conductor is zero. (This, also, is because of the free movement of charges. If there was a net electric field inside, the charges would rearrange because of it, and cancel it out.) Therefore, all the charge has to lie on the surface of the conductor.
Secondly, what is the electric field on the surface of a conductor? The electric field is zero inside a conductor. Just outside a conductor, the electric field lines are perpendicular to its surface, ending or beginning on charges on the surface. Any excess charge resides entirely on the surface or surfaces of a conductor.
Simply so, what is a charged conductor?
Charged Conductors. Suppose that we put a negative charge on an arbitrarily shaped, solid, conducting object. Instead, all of the excess charge must be distributed over the surface of the conductor. It follows that: Any excess charge on a solid conductor resides entirely on the outer surface of the conductor.
Why electric field is normal to the surface?
The charges on the surface of a conductor are static, that is, they do not experience any force. It is only when there is no component of electric field along the surface of charged body. Hence electric field is normal to the surface.
