A metal ion ${\mathrm{M}}^{\mathrm{n}+}$ having ${\mathrm{d}}^4$ valence electronic configuration combines with three didentate ligands to form a complex compound. Assuming ${∆}_{\mathrm{o}}>\mathrm{p}$, Write the electronic configuration of the valence electrons of the metal ${\mathrm{M}}^{\mathrm{n}+}$ ion in terms of ${\mathrm{t}}_{2\mathrm{g}}$ and ${\mathrm{e}}_{\mathrm{g}}$.
