State the hydridisation of central atom in `XeF_2` and `XeF_4` molecules.

Explanation

To determine the hybridization of the central atom in the molecules \( \text{XeF}_2 \) and \( \text{XeF}_4 \), we will follow these steps:

### Step 1: Determine the Valence Electrons of Xenon
Xenon (Xe) has an atomic number of 54. Its electron configuration is:
\[ \text{[Kr]} \, 4d^{10} \, 5s^2 \, 5p^6 \]
In the valence shell (5th shell), xenon has:
- 2 electrons in the 5s subshell
- 6 electrons in the 5p subshell
