1 CHAPTER 4 ATOMIC STUCTURES
2 SCHRODINGER WAVE EQUATION In 1926 Schrodinger wrote an equation that described both the particle and wave nature of the electron Schrodinger's equation can only be solved exactly for the hydrogen atom. Must approximate its solution for multi-electron systems. Wave function ( y ) describes: 1. energy of e - with a given y 2. probability of finding e - in a volume of space
8 O: 1 s 2 2 s 2 2 p 4 1s 2s 2p x 3s 2p y 2p z ENERGY LEVELS OF ELECTRONS Principal energy levels (shell) - electrons with the same value of n Designated by "n" n=1, n=2 and so on... If n=1 there is only one sublevel: s If n=2 there is two sublevels : s and p Space for electrons : If n=2, electron occupy in 1s, 2s and 2p x , 2p y , 2p z Subshell - electrons with the same values of n and l Orbital - electrons with the same values of n , l , and m l
