I have read that in a charged conductor, all the charge is located at the surface of the conductor and the Electric Field inside the conductor is zero.
Suppose we have a conductive sphere with charge Q = -4e.
Where exactly in the sphere are these 4 electrons? I know that they are "on the surface", but how exactly does this distribution that makes an Electric Field zero in ALL points of the sphere looks like?

Ultimately, the claim that the electric field inside a conductor is zero requires the charge distribution on the surface to be continuous, or at least nearly so. In the case of Q=-4e, there's no way to make the electric field exactly zero inside the conductor.
 
Yes iw ould say they would spred symmetrically
