Unformatted text preview: nucleus contain more potential (stored) energy. Example - Many of the chemical reactions that are associated with energy (ex: photosynthesis) involve electrons moving to higher or lower energy levels. Distribution of Electrons Electron Shells The different energy levels are also called electron shells . The first shell is the K shell, the next is the L, followed by M, N, etc. Electrons in the K shell have the least energy. Electrons that are further from the nucleus have more potential energy . The maximum number of electrons in each shell is given by the formula 2N 2 where N is the shell number. From this formula, the maximum number in each shell is 2, 8, 18, 32, etc. The maximum number of electrons in the last (outer) shell is 8....
