PHYS 117 Chapter Notes - Chapter 28: Correspondence Principle, Bohr Radius, Emission Spectrum
Document Summary
The wavelengths contained in an emission spectrum are characteristic of the element emitting the light. Absorption spectrum: an element can absorb light at specific wavelengths. The electron moves in circular orbits about the proton under the influence of the coulomb force of attraction. Only certain electron orbits are stable and allowed. Radiation is emitted by the hydrogen atom when the electron jumps from a more energetic initial state to a less energetic state. The frequency of the radiation is independent of the frequency of the electron"s orbital motion. The circumference of an electron"s orbit must contain an integral number of de broglie wavelengths. The electron can exist only in certain allowed orbits determined by the integer, n. Bohr radius: the orbit with the smallest radius. Ground state: lowest-energy state, n = 1. Ionization energy: the minimum energy required to ionize the atom (that is, to completely remove the electron)
