You may be correct, but what difference does it make? What magnitude of error would be introduced? We know that a 0.2 nm particles cannot exist because a single silver atom is 0.288 nm in diameter. We also know that the van der Waals' force exceeds 100,000 G forces for particles that small, and there is no counter force of repulsion that is strong enough to keep such small particles from aggregating to form larger particles. For this reason alone the existence of particles that size is unlikely. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
