Among cuprous and cupric, which has more stable configuration? Why? |
|
Answer» Solution :Electronic configuration of `Cu^(+)` (cuprous) is `[Ar]3d^(10)` and of `Cu^(2+)` (cupric) is `[Ar]3d^(9)` Cuprous has more stable configuration. This isbecause `d^(10)` is COMPLETELY filled d-subshell. Due to SPHERICAL symmetry, it is more stable configuration: |
