Ex.: 2 Ag+ + Zn = 2 Ag + Zn2+
The silver ions in the exposed area will be reduced to black metallic silver in a matter of minutes.
The total ionic equation shows all of the equation, even the spectator ions. The net ionic equation shows the net change after spectator ions have been removed.
The equation is: H2O------>H+ + OH-
The equation is: H2O------>H+ + OH-
Ions that appear on both sides of the equation are spectator ions. These ions do not participate in the reaction at all. Thus, they are omitted when writing the net ionic formula of a reaction.

Silver ions and Fluoride ions put together.
Silver ions are only one half of a ionic bond. Take a simple ionic compound, one half of which is silver, for example silver bromide. This contains both Ag2+ (silver) and Br-(Bromine) ions. The bonds between these two different ions are ionic bonds
Hydrated sodium, sulfate, silver, and nitrate ions. (The ions already exist in the sodium sulfate and silver nitrate solids, but may not be hydrated there.) since silver sulfate is not very soluble in water, most of the silver and sulfate ions will be removed from the water as solid precipitate, but some hydrated ions will remain in solution.
Two types: silver (Ag+) and chromate (CrO4-2) And within the formula (Ag2CrO4) there are two silver ions and one chromate ion for a total of three ions.
