Free electrons

  1. Oct 18, 2013 #1
    Electrons in the first energy level needs energy to go to the second energy level by absorbing photons and the electron can escape from its atom if the energy was high enough and be free. Now what's going to happen to this free electron after it escaped from its atom?

    It was helpful, but I still don't understand. What does a free electron do?
