Second Electron Shell Contains the 2s and the 2p orbitals 2s is also spherically symmetrical,but is not a simple exponential function 2☒ electron density node node distance -→distance from the from the nucleu nucleus node nucleus node Most of the electron density is further away,past a NODE(region of zero electron density).
