Explain why XeO4 has sp3 hybridization?

Xenon undergoes SP3 hybridization in the fourth excited in the formation of XeO4. In the fourth excited, xenon atom has 8 unpaired electrons. One “s” and three “p” – orbitals undergo sp3 hybridization. Since it has no lone pair of electrons, the shape of XeO4 is tetrahedral with the bond angle of 109 degrees. It has four sigma and four pie bonds.
