This bundle of PowerPoints covers IBDP Chemistry SL Topic 3.1: The Periodic Table – Classification of Elements (first examination 2025) and provides a complete, structured teaching sequence aligned to the updated IB specification. It is designed to build deep conceptual understanding of periodic trends, classification and electron configuration, while preparing students for exam-style explanations.

Topic 3.1 focuses on how elements are classified in the periodic table and how their position explains their properties. The periodic table is arranged by increasing atomic number and organised into groups, periods and blocks (s, p, d, f). In this bundle, students explore metals, non-metals and metalloids, group and period relationships, valence electron patterns, periodic trends in atomic radius, ionisation energy, electron affinity and electronegativity, as well as metallic and non-metallic character.

The bundle includes the following fully editable .pptx PowerPoint files:
• Structure of the Periodic Table
• Electrons and the Periodic Table
• Trends in Atomic and Ionic Radius
• Periodicity of Ionisation Energy, Electron Affinity and Electronegativity
• Group 1 and 17 Elements
• Metallic and Non-Metallic Continuum
• Oxidation States

Each lesson contains retrieval starters, clearly defined key terms, worked examples, explanations linked to effective nuclear charge and shielding, mini whiteboard practice, and exam-style questions with answers.

The sequence progresses logically from classification and electron configuration to periodic trends and reactivity (Group 1 metals and halogens), before linking structure to acid–base behaviour of Period 3 oxides and environmental chemistry (acid rain and ocean acidification). Oxidation states are included to support understanding of redox and naming conventions.

This bundle is ideal for full-topic teaching, consolidation or structured revision of SL 3.1 and supports conceptual understanding, IB Nature of Science links and strong explanation skills required for IB assessment.
