QeQ with a non-ReaxFF potential (UFF)

Dear Members.

Im trying to use charge Equilibriation method on ZnO with UFF potential, but I don´t find the parameters for Zn:

chi which denotes the electronegativity in eV,
eta which denotes the self-Coulomb potential in eV,
and which gamma denotes the valence orbital exponent.

Thanks in advanced

Best Wishes
