Smile Is this description for silicon in glass how much eV the electron needs to leave the

... ground state, and move to shell 2. Energy gap 1.12 eV? and also, Energy separation (EΓL) 4.2 eV Maybe its not the same silicone that goes into glass. When I Search for glass electron shell eV no websites get to the point with the answer. If I get a idea how much glass electrons need to get to shell 2, and 3, and how much electrons in SOLID black carbon need in eV to move to shell 2, and 3, it is going to help my study a lot. I am trying to get a rough idea of the eV in glass for the electron to get exited and leave the ground state, and go to shell 2, then 3. Because visible light does not excite the electron in glass, but UV does. solid state physics can be VERY DIFFERENT than atomic physics. When atoms are joined together to form a solid, their behavior can be very different than when they are isolated. There are no more "discrete energy states" at the low-lying range, because these have been replaced by energy BANDS!. If I take carbon atoms, and arrange it in one way, I get graphite. But I change the arrangement in another way, I get diamond! Two completely different types of material, and with different optical properties. Yet, each one of them is made of carbon! Thank you for your help, anything helps, even a few words.
