Explanation

The first three electrons fill the

\({t}_{2g}\) 𝑡2𝑔

Sv6Kpe[] orbitals singly.Sv6Kpe[]Sv6Kpe[]

The next three electrons pair up with the electrons already in the

\({t}_{2g}\) 𝑡2𝑔

Sv6Kpe[] orbitals.
This results in all six electrons occupying the

\({t}_{2g}\) 𝑡2𝑔

Sv6Kpe[] orbitals, and the

\({e}_{g}\) 𝑒𝑔

Sv6Kpe[] orbitals remain empty.Sv6Kpe[]
