What Happens on the Atomic Level When You Touch Something?

Do the atoms touch? Almost touch? Are there small reactions? Give me the full rundown.

They almost touch.

Electrons repell each other, this is called electrostatic repulsion. The closer they are together, the stronger the force that repels them is. So no atoms in your finger actually touch anything, they just get stopped by the electrons of the two objects repelling each other.

You need lots of energy for molecules to actually touch. Like in the Sun, for instance.
