Schrödinger’s model of the atom describes the electron as a standing wave: He chose to describe the energy of the electron. Thus position of the electron is uncertain . Ψ = Ψ E H     = = Ψ H a complex mathematical function of coordinates x , y , and z describing the electron as a wave. a complex mathematical operator like a cosine or a derivative
Important Points of Schrödinger’s Theory

Quantum Numbers Three numbers are required to describe the distribution of electrons in 3-D space. Ψ = fn( n , l , m l , m s )
The Principal Quantum Number (n) Indicates the size of the orbital or distance from the nucleus Rule: must be a positive integer 1, 2, 3 corresponds to Bohr’s n values for a hydrogen atom the higher the value of n , the higher the energy level We call these energy levels Electron Shells
