Ionisation potential and electron affinity of fluorine are `17.42` and `3.45eV` respectively .Calculate the electronegativity of fluorine on Mulliken scale and Pauling scale .

Explanation

To calculate the electronegativity of fluorine on the Mulliken scale and the Pauling scale, we will follow these steps:

### Step 1: Understand the formulas
- **Mulliken Scale**: The formula for electronegativity (EN) on the Mulliken scale is:
\[ \text{EN} = \frac{\text{Ionization Potential} + \text{Electron Affinity}}{2} \]
