LESSON 8 continued: Bohr's Model
BOHR (1920s)
> Rutherford's model was inherently unstable
- Protons and electrons should attract each other
> Matter emits light when it is heated (blackbody radiation)
> Light travels as photons
> The energy carried by photons depends on their wavelength
> Bohr based his model on the energy (light) emitted by different atoms
- Each atom has a specific spectra of light, and to explain this emission, Bohr suggested that electrons
occupy shells or orbitals
BOHR'S THEORY
> Electrons exist in orbitals
> When they absorb energy, they move to a higher orbital.
> As they fall from a higher orbital to a lower one, they release energy as a photon of light.
