water molecule



Does anyone know how much charge is associated with the oxygen atom and the hydrogen atoms in a water molecule? The chemistry books show "2delta -" and "delta +" but do not indicate what delta is. Nor do the websites I have visited so far.

I am trying to come up with an interesting problem similar to the "point charges located on the vertices of an equilateral triangle," dealing with electric fields and potential, but perhaps more "realistic" in the sense that the students may be better able to relate to the water molecule. Several of them are in AP Chemistry.

If anyone is aware of either data I can use or problems others have written, I would appreciate your help. Thanks
