Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: Fundamental Particles of the Atom, Evolution of Atomic Models, Electromagnetic Radiation and Spectra.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 44 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.

4
Day 7

Spaced Revision

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

What to Focus On

  • Electron: negative charge, very small mass
  • Proton: positive charge, mass ≈ 1840 × mass of electron
  • Neutron: no charge, mass slightly more than proton
  • Thomson’s model: electrons in a positive sphere
  • Rutherford’s experiment: α-particles scattered by gold foil
  • Rutherford’s conclusion: dense nucleus, electrons in empty space
  • EM radiation: transverse waves of electric and magnetic fields
  • Speed in vacuum: 3 × 10⁸ m/s
  • Energy is quantized: E = hν

Common Mistakes to Avoid

Electrons revolve around the nucleus in fixed circular orbits like planets around the sun, as per Bohr's model, and this applies to all atoms.

Orbit and orbital mean the same thing — both refer to the path of an electron around the nucleus.

The energy of electrons depends only on the principal quantum number (n), so 3s, 3p, and 3d have the same energy.

Memory Tips

Fundamental particles: electron, proton, neutron

Relative charges: electron (-1), proton (+1), neutron (0)
