Xenon does not form fluorides such as `XeF_(3)andXeF_(5)` Why ?

Explanation

All the filled orbitals of Xe have paired electron. The promotion of 1, 2 or 3 electrons from the `5p`-filled orbital to the `5d-`vacant orbitals will give rise to 2, 4 and 6 half-filled orbitals. Therefore, Xe can combine with even number of F atom but not odd. Thus, Xe doesn.t form `XeF_3 and XeF_5`.
