`Cu^(2+)` will have the following electronic configuration.A. `1 s^2, 2 s^2 2p^6, 3 s^2 3 p^6 3 d^10`B. `1 s^2, 2 s^2 2p^6, 3 s^2 3 p^6 3 d^9, 4 s^1`C. `1 s^2, 2 s^2 2 p^6, 3 s^2 3p^6 3 d^9`D. `1 s^2, 2 s^2 2 p^6, 3 s^2 3 p^6 3 d^10, 4 s^1`

Answer» Correct Answer - C
( c) Ground state of `Cu^29 = 1 s^2 2 s^2 2 p^6 3 s^2 3p^6 3 s^10 4 s^1`
`Cu^(2+) = 1 s^2 2 s^2 2p^6 3 s^2 3 p^6 3 d^9`.
