Recall that in a neutral atom, the number of electrons is equal to the number of protons.
Identify the atomic number of copper (Cu) from the periodic table, which represents the number of protons in the nucleus.
Note that the atomic number of copper is 29, meaning it has 29 protons.
Since the atom is neutral, the number of electrons must also be 29 to balance the positive charge of the protons.
Therefore, a neutral copper atom contains 29 electrons.
