Write electronic configuration of `Cu^(+2) ` and `Co^(+2)`

Explanation

To find the electronic configurations of \( \text{Cu}^{2+} \) and \( \text{Co}^{2+} \), we first need to understand the ground state electronic configurations of copper (Cu) and cobalt (Co) in their neutral forms.

### Step 1: Write the electronic configuration of neutral cobalt (Co).
- Cobalt has an atomic number of 27.
- The electronic configuration of cobalt is:
\[ \text{Co}: [\text{Ar}] \, 3d^7 \, 4s^2 \]
