Document Summary
Energy levels of h atom (qualitative derivation, quantitative understanding of variables) Quantitative understanding of variables: en=(-z2 e4 me)/(8epsilon2 n2 h2) H atom emission spectrum (transitions: lyman series n=6 2 n=1, balmer series n=63 n=2 (visible, paschen series n=6 4 n=3. Conversion between energy, wavelength, and frequency: know c= v and e=hv then you"ll be fine. Equations: c= v e=hv (will be given constants) 1/n2: quantized e and r to en and rn, using qualitative derivation lead to quantizing angular momentum. Indicates light exhibits wave-particle duality (which lays the foundation for quantum mechanics) The difference in these energies allows for many more transitions to be available. In addition, for helium when there is already an electron in the 1s orbital it causes each of the electrons to have different energies (due to electron-electron interaction). An additional reason for this difference has to do with electron spin.
