A colloidal particle is positive, but not as reactive as the > monoatomic silver. Pitty he does not speak *colloid science*. Silver Colloid particles are agrigates of either single silver ions (simple ions) creating complex ions, or simple ions and metallic atoms which will have a charge lower than the former. Monoatomic ions are reactive because of their size, multiatomic ions are able to accept more electrons per particle. > How the positive charge is created is not know by me.

Whilst an electron has a particular charge, the energy required to remove or gain one is different in each element, and the conductivity is therefore different also. The energy required to remove a second electron is much higher than to remove the first... an so on. > , it means there is either a missing electron or an extra > proton somewhere.

The manner of creating ions by electrolysis is well researched and straight forward, if not fully understood. One would need to add protons to create a positive charge, which would create a different element? Hydrogen ions (protons) have a positive charge and are unlikely to combine with silver (there are no silver hydrides). They are more likely to be reduced at the cathode as hydrogen gas. BTW, the zeta potential of a colloid is a measurement of the electrostatic repulsion between the charged particles and their Stern layers (neutralising layer of water molecules which travel with the particle) and the diffused layer, and derives its value from the charge on the particle, and is measured chiefly by measuring the particles mobility.
