Study Notes
Limitations of Rutherford Atom Model
- Rutherford's model is based on Newton's laws, which only apply to neutral bodies, not charged bodies like electrons moving around a positive nucleus.
- The analogy between planetary motion and electron motion fails because electrons repel each other, whereas planets attract each other through gravity, and electrostatic attraction is present in a nuclear atom model.
Inconsistencies with Electromagnetic Theory
- According to Maxwell's electromagnetic theory, a rotating electron would continuously radiate energy, losing kinetic energy and causing its orbit to shrink, ultimately falling into the nucleus, making the atom model unsustainable.
Spectral Inconsistencies
- Continuous emission of radiation would result in a continuous or band spectra, but atoms actually produce discontinuous or line spectra.
Unaddressed Aspects of the Model
- Rutherford's model does not provide information about the shape of the orbits.
- The model fails to explain the rotation of electrons in atoms with multiple electrons.
