Document Summary

The foundation of quantum mechanics is that of wave-particle duality. Use this to calculated the energies associated with the hydrogen line spectrum. Radical wavelength: depends on the distance from the nucleus. N = positive constant p(r) = polynomial in r. K = positive constant r = distance from the nucleus. Quantum numbers: to quantize certain properties of the electron. = angular momentum, shape, show atomic orbital, angular node. Ex: n= 3, = 2 type of orbital: 3d. Dirac merged schr dinger"s wave-equation with einstein"s theory of special relativity to produce the dirac equation, the spin quantum number is theoretically predicted. Degeneracy - for a hydrogen atom (or other single-electron species, he+, li2+, etc. only n determines the energy of each orbital. Orbitals with higher = have a higher energy at a constant n. Aufbau principle - aufbau in german means construction or building up. To fill orbitals they must be built up from the lowest to highest energies.
