This PowerPoint lesson explains how electron configuration links directly to the structure of the periodic table, helping IBDP Chemistry students predict atomic structure from position. Designed for first assessment 2025, it builds the essential skills needed to deduce electron configurations and interpret group and period trends with confidence.

The periodic table is arranged by increasing atomic number, and its structure reflects the arrangement of electrons in atoms. This lesson clearly shows how group number, period number, and block (s-, p-, d-, f-block) can be used to determine an element’s electron configuration up to Z = 36. Students learn how to write condensed electron configurations, identify valence electrons, and connect periodic position to atomic structure.

Clear worked examples are included for Group 1 (alkali metals) and Group 17 (halogens), demonstrating how elements in the same group share the same valence electron pattern (e.g. ns¹ or ns² np⁵). The lesson also introduces the block method for constructing configurations directly from the layout of the periodic table, offering an alternative to memorising filling-order diagrams.

Key groups such as alkali metals, transition elements, halogens, and noble gases are identified, with brief discussion of their characteristic properties. Links to environmental and CAS contexts, including mining and resource use, help students connect periodic structure to real-world issues.

The PowerPoint includes starter activities, clear learning outcomes, structured explanations, step-by-step examples, and practice questions suitable for classroom teaching, consolidation, or revision.

File type included: PowerPoint (.pptx)
Last updated: January 2026 – configuration examples refined, block explanations clarified, and content checked against the 2025 IB Chemistry syllabus.

BUNDLE S3 Classification of Matter, SL Content Only (IBDP Chemistry)

This bundle of PowerPoints covers the SL content of S3 Classification of Matter for IBDP Chemistry (first examination 2025), bringing together key ideas from the periodic table and introductory organic chemistry in one structured resource. It is designed to help students classify substances based on their structure, composition and properties, while building the knowledge needed for later topics in bonding, reactivity and analysis. In IBDP Chemistry, classification of matter involves organising elements and compounds into meaningful groups so that patterns in their behaviour can be understood and predicted. This bundle supports that aim through two major sections. S3.1 develops student understanding of the periodic table, including its structure, electron arrangement, atomic and ionic radius, periodic trends, Group 1 and Group 17 elements, the metallic and non-metallic continuum, and oxidation states. S3.2 then introduces the classification of organic compounds through types of formula, functional groups, homologous series, nomenclature of straight-chain and branched-chain compounds, and structural isomerism. This fully editable bundle includes 13 PowerPoint (.pptx) lessons: S3.1 Structure of the Periodic Table, Electrons and the Periodic Table, Trends in Atomic and Ionic Radius, Periodicity of Ionisation Energy/Electron Affinity/Electronegativity, Group 1 and 17 Elements, Metallic and Non-Metallic Continuum, and Oxidation States. S3.2 Types of Formula, Functional Groups, Homologous Series, Nomenclature of Straight-Chain Organic Compounds, Nomenclature of Branched-Chain Organic Compounds, and Structural Isomerism. Across the bundle, students are supported with retrieval starters, key word definitions, clear explanations, worked examples and practice questions with answers. These lessons are ideal for first teaching, revision, cover lessons or building a complete SL unit sequence aligned to the IBDP Chemistry specification for first examination 2025. File types included: editable PowerPoint (.pptx) files. Last updated: 2026 – improved sequencing, refined explanations, and enhanced practice activities across both periodicity and organic classification content.

BUNDLE S3.1 The Periodic Table: Classification of Elements, SL & HL (IBDP Chemistry)

This comprehensive PowerPoint bundle covers IBDP Chemistry S3.1 Periodic Table: classification of elements (SL & HL), including structure, periodic trends and transition elements. It provides a complete sequence of lessons designed to build deep understanding of how elements are organised and how their properties change across the periodic table. The periodic table is a systematic arrangement of elements by increasing atomic number, where patterns in physical and chemical properties repeat (periodicity). This bundle supports students in recognising these patterns and using them to explain trends in atomic structure, reactivity and bonding. Students develop understanding of metals, non-metals and metalloids, electron configurations, and key periodic trends such as ionisation energy, electronegativity and electron affinity . This bundle includes 11 fully editable PowerPoint (.pptx) lessons: • Structure of the periodic table • Electrons and the periodic table • Trends in atomic and ionic radius • Periodicity: ionisation energy, electron affinity and electronegativity • Group 1 and Group 17 elements • Metallic and non-metallic continuum • Oxidation states • HL: discontinuities in ionisation energy • HL: characteristic properties of transition elements • HL: variable oxidation states in transition elements • HL: coloured complexes of transition elements Each lesson includes retrieval starters, clear explanations, key definitions, worked examples and exam-style practice questions with answers. This resource is ideal for full topic delivery, revision, or structured lesson planning aligned to the IBDP Chemistry 2025 specification. File types included: • Editable PowerPoint (.pptx) lessons Last updated: 2026 – improved explanations of periodic trends and enhanced exam-style practice questions.

BUNDLE S3.1 The Periodic Table: Classification of Elements, SL Content (IBDP Chemistry)

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.
