A water soluble metal salt produces a solution when dissolved in water. Silver ions are water soluble and therefore form a solution. Since an ion is dissolved silver and not metallic silver it is not a particle. Silver ions have a positive ionic charge due to the missing electron. Elementary particles defined for quantum physics are not applicable when making a distinction of silver ions and silver particles. A silver particle is a small group of silver atoms held together by Van der Waals' force. A silver particle is metallic silver. Silver atoms have no ionic charge. Silver particles have a negative zeta potential charge when they exist in a low ionic environment like DI water. Metallic silver and ionic silver have vastly different physical properties. Metallic silver is not water soluble, while a silver ion is water soluble and cannot even exist without the water. If the water is removed you wind up with a silver compound not a silver ion. If water is evaporated from ionic silver, the silver cations are forced to form a compound with the companion anion that is present (there is always a companion anion for every cation). If no other anions are present then hydroxide (from dissociation of the water molecule) will form silver hydroxide when the water is evaporated. Particles can be separated by ultra centrifugation, ions cannot. 365,000 G-forces will easily separate particles of only two atomic diameters. 1 million G-forces will not separate ions.
