... The diameter of a US penny is 19 mm. The diameter of a silver atom, by comparison, is only 2.88 Å. How many silver atoms could be arranged side by side in a straight line across the diameter of a penny? Solution The unknown is the number of silver (Ag) atoms. We use the relationship 1 Ag atom = 2.88 ...
