Explanation:
The atomic number of Cu = 29
Valence electron configuration of Cu = 3d¹⁰4s¹
Cu+ is formed when 1 electron is lost from Cu. Therefore, the atomic number for Cu+ = 28
Similarly, loss of 2 electrons from Cu results in Cu2+ with an atomic number = 27
Cu+ is the larger ion. This is because as electrons are removed from the valence orbitals, the attraction between the outer electrons and the nucleus tends to increase which then results in a decrease in size.
Ans: Cu+ has one more electron
