Match each model to what it could NOT explain

Read exercise and reference answers
Matching pairs
  1. Left
    Thomson's model
    Right
    disproved by alpha-particle scattering
  2. Left
    Rutherford's model
    Right
    could not explain the atom's stability
  3. Left
    Bohr's model
    Right
    failed for multi-electron atoms
  4. Left
    Bohr's model again
    Right
    ignored the electron's wave nature
The failures are what drove the next model, and they are the examinable part. Source: syllabus Chemistry Part I, Ch 2 Structure of Atom.

Questions
  1. Statement is true
    Yes
    Statement
    Rutherford's alpha-particle scattering disproved Thomson's model.
  2. Statement is true
    Yes
    Statement
    Rutherford placed a tiny positive nucleus at the centre.
  3. Statement is true
    No
    Statement
    Rutherford's model explained why the electron does not fall in.
  4. Statement is true
    Yes
    Statement
    Rutherford's model resembles the solar system.
  5. Statement is true
    No
    Statement
    Rutherford's model described the energies of the electrons.
The scattering experiment settled the nucleus, but left stability unexplained. Source: syllabus Chemistry Part I, Ch 2 Structure of Atom.
