Problem: The gold foil that Rutherford used in his scattering experiment had a thickness of approximately 0.006 mm .If a single gold atom has a diameter of 2.9 10-10 m, how many atoms thick was Rutherfords foil?

🤓 Based on our data, we think this question is relevant for Professor Giles' class at VCU.

FREE Expert Solution
• We can calculate for how many atoms thick the foil is by dividing the thickness of gold foil by the diameter of a gold atom
• Setup a dimensional analysis with proper length conversion to determine the # of atoms
