If the distribution is spherically symmetric, yes for the field outside it. This isn't usually the case and the net force between two overall neutral atoms is typically repulsive at short distances and slightly attractive at those a little more than a certain value, after which it drops rapidly toward zero. Details can be found in books on the structure of materials.
