Quizplus · Accepted Answer

Electrons are negatively charged particles and are attracted towards positively charged protons in the nucleus. This electrostatic attraction between electrons and protons keeps the electrons bound to their atoms and prevents them from flying off the surface of the coin. While mutual repulsion between electrons also plays a role, this is not the main reason why electrons in a coin don't fly off.
