Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Early ideas about atomic structure, 2. Rutherford's alpha-particle scattering experiment, 3. Rutherford's nuclear model and its limitations.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 97 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Atoms after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Electrons were discovered in 1897 by J. J. Thomson.
  • Atoms are electrically neutral, so positive charge must also be present.
  • Thomson proposed the plum pudding model in 1898.
  • Rutherford proposed the alpha-scattering experiment in 1906.
  • Geiger and Marsden performed the experiment around 1911.
  • The alpha-particle beam energy was 5.5 MeV and the foil was gold.
  • Rutherford’s model has two main difficulties.
  • It predicts instability because orbiting electrons should radiate energy continuously.
  • It cannot explain line spectra.

Common Mistakes to Avoid

The alpha particle in Rutherford scattering hits the gold nucleus directly when it turns back.

The distance of closest approach is the same as the radius of the nucleus.

Rutherford’s model is stable because electrons keep moving in circular orbits.
