The Bohr model explains atomic energy levels and emission spectra. This video shows why it worked and where it breaks down. You'll learn how electrons occupy energy levels, how they jump between orbits, and how those transitions produce the colorful hydrogen emission spectrum.

OpenStax Chemistry 2e, Figure 6.13 Compare the two types of emission spectra: continuous spectrum of white light (top) and the line
spectra of the light from excited sodium, hydrogen, calcium, and mercury atoms. Continuous spectrum and emission spectrum of calcium were used to show continuous and discrete spectra of a rainbow.
