In the fourth excited state xenon atom, has 8 unpaired electrons
One s and three p orbital undergo $s p^{3}$ hybridization. Four $sp^{3}$ hybrid orbitals form four $\sigma $ bonds with oxygen atoms. They are $\sigma \, s p^{3} \, -p$ . Four $p\pi -d\pi $ bonds are also formed with oxygen atoms by the unpaired electrons.
