The hybridization of xenon in XeF₆ is:
In XeF₆ , xenon has 8 valence electrons, forms 6 bonds (12 electrons used), leaving 2 electrons as 1 lone pair. With 7 electron pairs (6 bonding, 1 lone), it adopts sp³d² hybridization, forming an octahedral electron geometry with a distorted octahedral molecular shape due to lone pair repulsion.
