Don't worry! I'm here to help. The atomic number of copper (Cu) is 29. This means that the copper nucleus contains 29 protons. As mentioned earlier, each proton has a charge of +1. Therefore, the charge on a copper nucleus is +29.

Remember, you can always refer to the periodic table to find the atomic number of an element and determine the charge on its nucleus.
