Question

When two bodies are brought face to face and they attract each other than what happens​

Answer 1

If they attract, it means they are oppositely charges atoms.
Any one of the atom donates or loses its electron and the other atom of athkr body accepts the electron thus forming a compound.

Instead of exchanging electrons, if they are rub against each other then they may just get charged by electrostatic force.
