Unformatted text preview: he electron wavelengths are described by the de Broglie relationship. Nobel Prize, Physics 1929 Only good for H and Hlike atoms Not good for heavier atoms • De Broglie’s assertion was verified by Davisson & Germer within two years. • Consequently, we now know that electrons (in fact - all particles) have both a particle and a wave like character. 4 1/21/2014 Quantum Mechanical Model of Atom: Wave Mechanics • Erwin Schrödinger made a profound discovery in 1927 by showing that the discrete energy states of matter could be determined by Wave Equations Atomic Orbitals described by the Schrödinger Equation • Schrödinger equation calculates the energy level of an electron that corresponds to its specific wavefunction. Schrödinger Equation Nobel Prize, Physics 1933 Hamiltonian Operator to the ψ function :D Quantum Mechanical Model of Atom: Matrix Mechanics leads to Uncertainty Principle • The observer can never exactly know both the position and momentum of a particle. Werner Heisenberg, Nobel Prize, Physics 1932 • As every observation requires an energy exchange (photon) to c...
