Why do the atoms in a piece of copper metal have no net charge? -the charges of the positive and negative copper ions cancel each other out. -the number of electrons surrounding each copper nucleus doesnât change. -copper atoms canât lose electrons without a substance present to gain electrons. -when a copper atom loses electrons, it also loses a corresponding number of protons. -the copper atoms exchange neutrons instead of electrons.
