               SUBTOPIC- Schrodinger wave equation, orbit and orbital concept.

               KEY NOTES :


                 The branch of science that takes into account this dual behaviour of matter

                    is called quantum mechanics.

                 Schrodinger wave equation is based on it.


                 He  was  able  to  explain  the  movement  of  electron  in  three  dimensional

                    space around the nucleus.


                      The equation can be written as

                                        8 m      ( V       )     0
                                         2
                                                      2
                   2
                              2
                                                             E
                 x  2      y  2      z  2        h 2

               Where Ψ is the wave function


                            x, y, z are Cartesian coordinates.


                            m is the mass of electron


                           E is the total energy


                           V is the potential energy


                           H is the Planck's constant


                 This equation can also be written as ĤΨ = EΨ


                       Where Ĥ is Hamiltonian operator
