How many atoms thick is aluminum foil? Asked by: David A. Biche Answer Approximately 193,000 atoms thick. This is a fairly rough estimate, from classroom data. We took squares of aluminum foil, measured the surface area and mass. By dividing the mass by a known density value, we obtained the volume of aluminum foil in our sample.

Approximately 193,000 atoms thick. This is a fairly rough estimate, from classroom data. We took squares of aluminum foil, measured the surface area and mass.
