A single "dissolved" atom of Ag is still a metal. It does not stop being,
by definition, a "metal" when it is a single atom in water.
A clump of silver, regardless of size, or charge, is still not
"dissolved". It is by definition, a colloid.

Not sure who you were addressing James, but I agree an atom = metal = element!
The definition of a colloid seems to have many experts and thus answers, but
I think you went amiss with a piece of silver = colloid! I would request
Ivan to give
us his wisdom on the "prefered" definition but as I recall, it requires a
charge on
the particles and they must be bigger then atoms! The other constraints, I
believe,
were that a colloid can not be a solution, dispersion nor suspension.
