32.4 Bohr Model of the Atom

Niels Bohr's Planetary Model

Something that is said to be quantized simply means that it is made of a number of fundamental units. Bohr applied the quantum hypothesis to the structure of the atom to explain atomic spectra. Duration: 5:21.

Bohr's Explanation of Atomic Spectra

Bohr proposed that electrons are restricted to particular orbits which he designated by principal quantum numbers. When electrons drop to lower energy levels, they emit light, giving rise to a specific atomic spectra. Duration: 4:56.
