what charge does silver have
The difference between silver ions and silver particles boils down to the fact that silver ions combine with chloride ions to form silver chloride and silver particles do not. This simple fact should be kept in mind when reading claims that silver ions are particles that can survive inside the body. A silver cation has a position charge (+1 valence) because it is missing one electron. The chloride anion has a negative charge (-1 valence) because it has one extra electron.
