Zero.
Explanation:
Electronegativity is a measure of how well an atom can pull electrons to itself.
If two atoms in a bond have different electronegativities, the electron density will be pulled towards the atom with the higher electronegativity, i.e. in
However, if it was the same on both atoms, they would have an equal pull on the electrons.
For example,
