Dry TEM samples
If the oxide particle checks at 100 nanometers, the ion is still the same small size.
If the oxide particle resulted from oxidizing a single ion, it will be 'way' small...and represent the ion and/or any "dissolved" products rather than any particles that might have been "suspended" in the liquid.
Most likely, that liquid sample didn't have ANY "suspended" particles at all before preparation.
If those same oxide particles clump up while drying the sample, it'll show huge particles where none anywhere near that size may have existed before the drying step.

Ode, I don't understand your problem, a silver oxide particle is larger than an a silver ion. So if the silver oxide particle checks at 1 nanometer then you know that the ion is smaller.<<<<
