Not even close, a gold atom is about 140 pm, while the diffraction limit for optical microscopes is around 200 nm, so 1000 Times bigger. And this does not mean that you could see a 200 nm object, only that you can differentiate 2 objects that are at least 200 nm apart. https://en.wikipedia.org/wiki/Diffraction-limited_system
So no it is not possible to see atoms with visible light photons.
