If you have a sphere of metal electrically isolated by a vacuum, and continuously add negative charge to it, the metal will eventually discharge due to field electron emission. This depends primarily on the work function.
Take the same situation as above, but continuously remove negative charge from the sphere. I know that the positive charge will accumulate on the outside of the metal sphere - how much negative charge can you remove before the skin of the sphere starts shedding?
