So I know glass is transparent because the electrons have energy bands(or the energy to get it up to the next energy state) that are beyond the energy of visible light. But what I what to know is why do the electrons have energy bands because every single electron is the same and there all fundamental so why do some electrons have small band widths(like the ones in brick) and others have large band widths(like the ones in glass)?
