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.

Parent didn’t say resolve, they said see — you can’t resolve stars but you can most certainly see them.
Light up a single atom enough and you can see it (unclear if this works with a dark adjusted naked eye or if a long exposure is required): https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/
