CHM120H5 Lecture Notes - Lecture 6: Azimuthal Quantum Number, Magnetic Quantum Number, Angular Momentum
Document Summary
The model of the atom (lecture 4 - 6) Bohr circular orbits of electrons around central nucleus of protons; quantization of orbital angular momentum; principal quantum number, n. Attractive force of electrons must be equal to centrifugal force of electrons, otherwise electrons would fly out of orbit. 2. 178x10-18(1/n2) or 1312kj/mol (this is the ionization energy of hydrogen) The h emission spectrum equation spectra gave the same value. Summerfeld elliptical orbits; azimuthal quantum number, l. Goudsmit and uhlenbeck spin quantum number, s. Observed 2 lines together, decided that there must have been 2 directions. Schro dinger wave equation model (1926) de broglie postulated wave particle duality of the. Standing wave: if radius of orbit is fixed, wave can have only certain values of lamda and therefore only certain. Frequencies and energies electron, = h/mv o o. 2 r = n = nh/mv h/ = mv. Davisson and germer demonstrated the wave nature of the electron.
