An atom loses an electron… It says, “Man, I really gotta keep an ion them.”
Two atoms are walking down the street and they run in to each other. One says to the other, “Are you all right?” “No, I lost an electron!” “Are you sure?” “Yeah, I’m positive!”
Two atom soldiers are fighting against an army. One gets shot. He cried out, im hit! I think I’ve lost an electron! Are you sure? Asks the other. Im positive!
This one as actually physics(unlike some other joke here, ahem cough cough)
