Right, on the huge hypothetical atom I asked about before; what I'm really after is how the electric field from a point charge is quantized at a macroscopic distance of several centimeters? Let's say that you charge a metal electrode with C Coulombs of negative charge and then use that electric field to accelerate a proton, say five centimeters away. Let's say that the voltage is 10 kV or something like that. Now, how is the electric field quantized? Is acceleration of the proton in "steps" and of so, how large are the steps? Is there an easy way of calculating the quantization of fields and if so, how is that done?
