Lesso Summaries
Lesson 1 – Principal Energy Levels & Ionisation Energy
Covers quantum shells, simple electronic structure, emission spectra, first ionisation energy and successive IEs. Includes quick AfL tasks and worked equations.
Lesson 2 – Factors Affecting Ionisation Energies
Explains nuclear charge, distance from nucleus, shielding and spin-pair repulsion. Students interpret real IE data to deduce the Periodic Table position.
Lesson 3 – Electrons, Orbitals & Subshells
Introduces s, p, d subshells, electron capacities and orbital shapes. Includes diagrams, animations and a simple practical activity modelling orbitals.
Lesson 4 – Electron Configuration (1s² notation)
Covers Aufbau, Hund and Pauli rules; electron configurations up to Ar; transitions into 4s/3d; configurations of ions. Includes multiple worked examples.
Lesson 5 – Electrons in Boxes Notation
Box-notation practice applying all three filling rules. Students write configurations for atoms and ions and identify free radicals.
Lesson 6 – Atomic Radii & Ionisation Energy Trends
Explores trends across a period and down a group, including anomalies (Li, Be → B). Includes interpretation of graphs and exam-style questions.
Final slides support consolidation of Chapters 1 & 2, with the coursebook questions and answers textbook exam-style questions and answers.
