Document Summary
Chem 130: general chemistry: macroscopic investigations and reaction principles - Lecture 19: the bohr theory & quantum mechanics. A spectrum containing light of all wavelengths, like the light of a rainbow. A spectrum showing only certain colors or specific wavelengths of light. Bohr established postulates to account for the stability of the hydrogen atom and the line spectrum of the atom. An electron can have only specific energy values in an atom, called its energy levels. Therefore the atom itself can have only specific total energy levels. Energy levels of the electron in the hydrogen atom can be derived by e = An electron in an atom can change energy only by going from one energy level to another energy level. By doing so, the electron undergoes a transition. The energy of the emitted photon, hv, equals the positive energy lost by the atom (- e) Hv = - e = -(ef - ei)
