Study Notes
Rutherford's Atomic Model
- Rutherford's model proposes an atom with a central, positively charged nucleus, containing most of the atom's mass.
- Electrons orbit the nucleus, similar to planets orbiting the sun.
- Most of the atom is empty space.
Nucleus
- The nucleus is small, positively charged, and contains nearly all the atom's mass.
- The nucleus contains protons and neutrons.
Extra Nuclear Part
- The empty space surrounding the nucleus is where electrons reside.
- Electrons orbit the nucleus in specific paths (shells or orbits).
- Electrons move at high speeds.
Drawbacks of Rutherford's Model
- The model fails to explain the stability of an atom.
- According to electromagnetic theory, orbiting electrons should continuously lose energy and spiral into the nucleus.
- Observation of emission spectra (discontinuous line spectra) contradicts the predicted continuous spectrum from orbiting electrons.
