Chances are, you can feel an atom. Below is from New Scientist Daily, from England.
"The human fingertip can distinguish between materials with only minuscule chemical differences – even a change as small as a single atom. Generally, what we feel with our fingertips are physical bumps in the surface structure of a material, but researchers asked whether it would be possible to feel a chemical difference, in which the internal molecular structures of two materials are slightly different but the surfaces are equally smooth.
In one test, where the only difference between two compounds was the substitution of a single carbon atom for a nitrogen one, the testers could tell the two apart with more than 68 per cent accuracy. This could be useful for visually impaired people or to make textures in virtual reality that feel real."
A typical carbon atomic diameter is 0.3 nm.
That's very small.

Atoms are small? Is this common knowledge?
Hell, my mother-in-law could find an invisible speck of dust on a table top at midnight in a dark room and pick it up on her finger tip. Science has nothing on her.

Does party affiliation play into this ? ;-)

I saw some dust under my table. Dust is filled with atoms. We are made up with billions atoms. I think someone is coming or going under my dinning room table.

That's impressive. As is my wife, who can hear a mouse fart across the street. She even knows what I'm thinking . . . before I've thunk it.
