State the total number of electron pairs surrounding the central atom in `XeF_2,XeF_4` and `XeF_6`.

Explanation

To determine the total number of electron pairs surrounding the central atom in the compounds \(XeF_2\), \(XeF_4\), and \(XeF_6\), we will follow these steps:

### Step 1: Determine the valence electrons of Xenon
Xenon (Xe) is a noble gas with an atomic number of 54. It has 8 valence electrons (2 from the s-orbital and 6 from the p-orbital).

### Step 2: Analyze the structure of \(XeF_2\)
- **Bonding**: Xenon forms 2 bonds with fluorine atoms.
- **Lone pairs**: Since xenon has 8 valence electrons and uses 2 for bonding, it has \(8 - 2 = 6\) electrons left, which form 3 lone pairs.
