On the Pauling scale, fluorine is assigned electronegativity 4.0, the maximum value used as the reference point for the whole scale.

Electronegativity measures an atom's tendency to attract the shared pair of electrons in a covalent bond toward itself. On the Pauling scale (the most commonly used scale, based on bond energy differences), values range roughly from about 0.7 (for caesium, the least electronegative common element) up to 4.0 for fluorine, the most electronegative element of all.
