Hydrogen Emission Spectrum Using Bohr Model
Hydrogen Emission Spectrum Using Bohr Model
The Bohr atomic model was long ago superseded by modern quantum mechanics. The one system for which it does give correct results is the hydrogen atom. This Demonstration models a hydrogen atom with 10 energy levels. An electron can fall to a lower energy level or get excited to a higher energy level. If the electron falls to the second energy level (Balmer series), then it emits a colored photon; the color depends on the wavelength. A photon can also excite the electron to a higher energy level. The levels with are actually degenerate and depend on additional quantum numbers ( and ).
