a: atom ~
b: rural community


"A more accurate depiction of an atom, showing it is mostly empty space (grey area) traversed by rapidly moving electrons (blue dots, drawn much larger than to scale) with the heavy nucleus (red and white dot at center, drawn larger than to scale) at center. Its shape is like that of a rural community, with expanses of uninhabited land, a few scattered farm houses, and a small village with closely packed houses at its center."

See the link for a realistic description of an atom.
