The dimensions of an atom are of the order of an Angstrom. Thus there must be large electric fields between the protons and electrons. Why, then is the electrostatic field inside a conductor zero ?

In any neutral atom, the number of electrons and protons are equal and the protons and electrons are bound into an atom with distinct and independent existence.
Electrostatic fields are caused by the presence of excess charges. But, there can be no excess charge on the inter surface of an isolated conductor. So, the electrostatic fields inside a conductor is zero despite the fact that the dimensions of an atom are of the order of an Angstrom.
