The radius of a copper (Cu) atom is roughly 1.3 × 10−10 m. How many times can you divide evenly a 223.3−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.)
