A small piece of aluminum (atomic number 13) contains 1015 atoms. (The atomic number is the number of protons; it determines the (positive) electric charge of the nucleus and, thus, the number of electrons in a neutral atom.) If the piece of aluminum has a net positive charge of 3.0 uC, what fraction of the electrons that the aluminum had when it was neutral would have had to be lost?
