Question

Using the shell thickness of your penny, calculate the number of copper atoms that extend across the shell of your penny. Assume that the atomic radius of copper is 1.28•10^-8 cm Shell Thinkness is 1.528•10^-3cm I don't know if this matters but the overall thickness of the penny is 0.152cm Using the shell thickness of your penny, calculate the number of copper atoms that extend across the shell of your penny. Assume that the atomic radius of copper is 1.28•10^-8 cm Shell Thinkness is 1.528•10^-3cm I don't know if this matters but the overall thickness of the penny is 0.152cm Using the shell thickness of your penny, calculate the number of copper atoms that extend across the shell of your penny.

Explanation / Answer

atomic radius of copper is 1.28•10^-8 cm

=>atomic diameter of copper is 2.56•10^-8 cm

Therefore, number of copper atoms that extend across the shell of penny = 1.528•10^-3 / 2.56•10^-8 = 59687 atoms
