The answer to each of the following questions is a single digit integer ranging from 0 to 9.
On the Pauling scale the electronegativity of fluorine is.

Explanation

To find the electronegativity of fluorine on the Pauling scale, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Electronegativity**: Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is a dimensionless quantity.

2. **Identify the Scale**: The Pauling scale is one of the most commonly used scales to measure electronegativity. It was developed by Linus Pauling in 1935.

3. **Find the Value for Fluorine**: According to the Pauling scale, fluorine is known to be the most electronegative element.

4. **State the Electronegativity Value**: The electronegativity of fluorine is approximately 3.9 on the Pauling scale.

5. **Round the Value**: Since the question asks for a single digit integer ranging from 0 to 9, we round 3.9 to the nearest whole number, which is 4.

### Final Answer:
The electronegativity of fluorine on the Pauling scale is **4**.
