An ion means charged particle. The simplest ion would be an electron(-) or proton (H+) Ag+ is a positively charged ion. electrically charged silver particle and ion are the same thing.. the charged particle, ion could be an electron/proton, atom, molecule, or "cluster of molecules" I'm not clear about all the particle size stuff myself. from my understanding of things like charges repel. Ag+ ions will remain separate unless they cluster as a result of other microelectrical forces.
