Electronic configuration of copper is 3d...

Electronic configuration of copper is `3d^(10)4s^(1)` instead of `3d^(9) 4s^(1)`.Why? 

Text Solution

Verified by Experts

The configuration of copper is `3d^(10) 4s^(1)` due to the extra stbility of `d^(10)` system in which all 10 electrons are completely paired and 3d-subshell in completely filled.
