What is the electron configuration of #Cu^+#? Chemistry Electron Configuration Electron Configuration 1 Answer anor277 Sep 6, 2017 Well we got copper, #Z=29#......... Explanation: And thus for the #"cuprous ion"#, #Cu^+#, we gots 28 electrons to distribute: #1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)# And for the #"cupric ion"#, #Cu^(2+)#, we gots 27 electrons to distribute: #1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(9)# Answer link Related questions How do electron configurations in the same group compare?
