Study Notes
Rutherford's Atomic Model Limitations
- Rutherford's model, with electrons orbiting a positive nucleus, failed to explain why electrons didn't lose energy and spiral into the nucleus.
- The model also couldn't explain the observed discrete (line) spectra of light, which contradicted the prediction of a continuous spectrum.
Bohr's Atomic Model
- Postulate 1: Electrons revolve around the nucleus in specific circular paths called orbits, each having a fixed energy level.
- Postulate 2: Electrons in these stable orbits neither emit nor absorb energy.
- Postulate 3: The further an electron's orbit is from the nucleus, the higher its energy level.
