Which will have a higher value of electronegativity for fluorine, the pauling scale or mulliken scale?

Answer

To determine which scale has a higher value of electronegativity for fluorine, we will compare the Pauling scale and the Mulliken scale. Here’s a step-by-step solution:

### Step 1: Understand the Electronegativity Scales
- The Pauling scale and the Mulliken scale are two different methods used to measure electronegativity.
- The Pauling scale is a widely used scale that assigns values based on bond energies, while the Mulliken scale is based on the average of the ionization energy and electron affinity of an element.

### Step 2: Know the Value of Fluorine on the Pauling Scale
- The electronegativity of fluorine on the Pauling scale is known to be approximately **4.0**.

### Step 3: Calculate the Mulliken Value
- The Mulliken scale value is related to the Pauling scale value. It is stated that the Mulliken value is approximately **2.8 times** the Pauling value.
- Therefore, to find the Mulliken value for fluorine, we multiply the Pauling value by 2.8:
\[ \text{Mulliken value} = 2.8 \times \text{Pauling value} = 2.8 \times 4.0 = 11.2 \]

### Step 4: Compare the Values
- From the calculations:
- Pauling scale value for fluorine = **4.0**
- Mulliken scale value for fluorine = **11.2**
- Clearly, the Mulliken scale value (11.2) is higher than the Pauling scale value (4.0).

### Conclusion
- Therefore, the Mulliken scale has a higher value of electronegativity for fluorine compared to the Pauling scale.
