Chapter 1, Problem 106AP

The radius of a copper $\left(\text{Cu}\right)$ atom is roughly $\text{1}{\text{.3 × 10}}^{\text{-10}}\text{m}$. How many times can you divide evenly a 10-cm-long piece of copper wire until it is reduced to two separate copper atoms? (Assume there are appropriate tools for this procedure and that copper atoms are lined up in a straight line, in contact with each other. Round off your answer to an integer.)
