How is the electrification of bodies?

Question

Electronics

How does the electrification of electrically neutral bodies occur? Suppose when rubbing paper on glass. Initially, both bodies are electrically neutral, then, as they write everywhere, electrons pass from one body to another under the action of friction. They write that when the friction force is stronger than the attraction of electrons to the nucleus of an atom, they move to another body, but why? Why does an electrically neutral body accept electrons?

Answer 1

I already answered a similar question here, and there, in the next answer from ittakir , there is an answer to yours.
There is such a physical parameter - the work function of an electron, it is different for different materials. And when they come into contact, due to the difference in the work function, the electron can jump to another material, and after separation it remains there. That's electrification for you.

Answer 2

Static electricity
