Xenon undergoes $\mathrm{s}{\mathrm{p}}^3$ hybridization

In the fourth excited state xenon atom, has 8 unpaired electrons

One $\text{s}$ and three $\text{p}$ orbital undergo ${\text{sp}}^{\text{3}}$ hybridization. Four $\mathrm{s}{\mathrm{p}}^3$ hybrid orbitals form four σ bonds with oxygen atoms. They are $\text{σ}{\text{sp}}^{\text{3}}-\text{p}$. Four pπ – dπ bonds are also formed with oxygen atoms by the unpaired electrons.
