Hybridization of Xenon

    1. The problem statement, all variables and given/known data

    When we hybridize xenon, do we excite one electron each from its 5s and 5p orbitals to its d orbital?

    I know the ground state xenon looks something like this:

    But when it's hybridized does Xenon look like this?

    Of the 5s and 5p electrons in the outermost orbit of Xe, two of the 5p orbital electrons get excited to the vacant 5 d orbital resulting in 4 unpaired hybridized electrons, 2 in 5p and 2 in 5d orbitals.

    d-electrons play no mayor role in bonding in Xenon compounds. Especially there are no spd hybrid orbitals involved in bonding.

    But how does xenon form so many bonds such as in xeF4

    As I am not good in drawing in this forum, let's look at XeF2 instead:
    You can write two mesomeric resonance structures:
    F- Xe-F <-> F-Xe F-
    In the case of XeF4, there are correspondingly 6 resonance structures with two F- atoms and two covalently bonded F. The bonding involves mainly the p orbitals on Xe, I don't think that hybridizing Xe will lead to any improvement.
