Ionization is when an electron is removed from an atom and ionization energy is the energy required to do this. "Electrons stream from the negative electrode to the positive electrode. In the process of moving from one electrode to the other they knock electrons in the enclosed gas to higher energy levels. In many cases the electron is completely removed from the gas atom." I'm completely unsure of this but does the color of the neon sign depend on how high the ionization energy level needs to be to remove the electron from the gas atom?
