help, example of "simulate metal in water by colloid potential"

Dear all
Hello
I saw the movie of “colloids in solvent” from http://lammps.sandia.gov/movies.html#colloid and read it’s input file. It had simulated Br colloids of diameter 5 in Hydrogen solvent by colloid potential.

colloid potential

pair_style colloid 12.5
pair_coeff 1 1 1.0 1.0 5.0 5.0 12.5
pair_coeff 1 2 5.0 1.0 5.0 0.0 7.0
pair_coeff 2 2 10.0 1.0 0.0 0.0 2.5

I need an example like it, that simulate any metal like gold in water solvent by colloid potential.
If you have, Could you help me and send some examples about that? I need value of pair-coeffitiont.

Figuring out the input parameters for your model
is a task you have to figure out. No one is likely to
do it for you.
