Document Summary
Atomic spectra: interpreting the frequencies emitted by atoms tells us something about them, note: couldn"t be explained classically either. Interpretation: atomic spectra allow us to infer what atoms do, they have only certain energy levels. Bohr atom: key advance was suggested by neils bohr, only certain distances were stable orbits, (essentially quantized the energy of atoms, closer to nucleus - lower energy level, further from nucleus - higher energy level, transitions involve light. Quantum number rules: principle quantum number, n=1, 2, 3, 4, 5: secondary quantum number: l=0, 1, n-1. Provides letter designation: s, p, d, f: magnetic quantum number: ml, -l, -l+1, 0, , l-1, l. Pictures of orbitals: perhaps the most important component of electron orbitals is their shape, drawings on the board, note concept of directional , note the concept of node. Orbital energies: for multi-electron atoms, the energies of the orbitals are known, 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s,
