gonelli Posted July 21, 2007 Share Posted July 21, 2007 I know that when you rub a balloon against your hair or a piece of wool that electrons are stripped from them and go across to the balloon, giving the balloon a negative charge. And you can rub a glass rod with a piece of silk and the rod loses electrons, making it positive. But what I don't understand is why the electrons move across to the different materials. What property of the material determines whether it will lose or gain electrons? Any help would be great. Link to comment Share on other sites More sharing options...
