Can you see a nucleus with a microscope?

I'm wondering if you can see the nucleus and actually determine that the periodic table of elements is correct on plutonium 239, I've never seen an actual picture only models and animations. Is it just theory and mathematics that these models and animations are proven through experimentation? I'm not a scientist or mathematician I think thats pretty obvious. And electrons that's another one that confuses me. I watched this documentary on energy and water, and how the history and treatment of the water effects it's energy. They were saying that the purification process destroys the symmetry of the water on every corner and angle that it was to turn, making it impossible for the water to sustain minerals and electrons or something like that. So by the time we drink it, it's absorbing the minerals and electrolytes from out body to regulate it's self because it's pretty much weak and retarded. But that a whole other story.
