Verified step by step guidance1
Identify the electron configuration of a neutral copper atom (Cu).
Determine the electron configuration of the copper 1+ ion (Cu^+).
Explain the concept of paramagnetism, which occurs when there are unpaired electrons in an atom or ion.
Analyze the electron configuration of neutral copper to identify any unpaired electrons.
Compare the electron configuration of Cu^+ to see if there are any unpaired electrons, explaining why it is not paramagnetic.
