Study Notes
Rutherford's Model of the Atom
- Asserts that the nucleus contains nearly all the atom's mass and positive charge.
- Electrons are posited to move in circular orbits around the nucleus.
- Proposes a strong electrostatic attraction between positively charged nucleus and negatively charged electrons.
Limitations of Rutherford's Model
- Fails to explain the stability of electrons as they revolve around the nucleus.
- Does not account for the electronic structure of atoms or the arrangement of electrons in different energy levels.
