If a positively charged hand touches a neutral state aluminum door knob with a composition of 3 valence electrons, 8 outer electrons, and 2 inner electrons, the three valence electrons will jump towards the hand and the door knob will turn into ionized aluminum (Al3+).How does the aluminum get the 3 valence electrons back and return to neutral aluminum (Al) ???
For the charge you are talking about, the amount of electrons is not too largeIt can take missing electrons from the surroundings.
