In the videos I had seen that the metals are at the verge of losing electrons and it can happen due to losing of an electron by a nearby atom or due to a charge ,,but I m confused if it loses electrons then it will get attracted to the positive nucleus then how can the electrons flow ??? How do the electrons carry energy? Please attach a video along with the answer.
