-Rutherford'd model was inherently unstable
- Protons & electrons should attract eachother
- Matter emits light when it is heated (blackbody radiation)
- Light travels as photons
- the energy photons carry depends on their wavelength
Separate the white light into colours with a diffraction granting or prism
Each line represents a photon of light emitted from the excited atom
These are unique sets of lines for each element
-Bohr based his model on the energy (light) emitted by different atoms
- Each atom has a specific spectrum of light
Examples of different atom spectrums of light:
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
- JanCarlo Paysan
