Ions cannot combine to form particles unless they take on an electron which converts them back into atoms. Only atoms can combine to form particles. Atoms do not have mutual repulsion because there is no ionic charge, so the van der Waal's force will act on the atoms pulling them together to form particles. For details see: http://www.silver-colloids.com/Papers/definitions.html#vanderwaal Once the particles grow beyond a few atoms, they develop the surface charge the creates the double electric layer which causes the "zeta potential'. When the zeta potential is sufficiently strong it will cause mutual repulsion of the particles to prevent the particles from growing larger. The mutual repulsion of ions is over one hundred thousand G-forces when they are within an atomic diameters of each other. There is no known force that will overcome such a high mutual repulsive force. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
