This PowerPoint lesson explains the physical properties and applications of metals, linking observable properties directly to metallic bonding and structure. Designed for IBDP Chemistry (first assessment 2025), it helps students move beyond memorisation to a deeper, structure-based understanding required for exam success.

The physical properties of metals arise from the presence of metal cations arranged in a lattice and a sea of delocalised electrons. This lesson clearly defines key terms such as malleability, ductility, electrical conductivity, and thermal conductivity, and shows how each property can be explained using the free-electron (electron-sea) model. Students learn how non-directional metallic bonding allows layers of ions to slide without the structure breaking, and why mobile electrons are essential for conduction.

The PowerPoint explores common metallic properties including lustre, sonority, malleability, ductility, and conductivity, with explicit links back to bonding and structure. Trends in electrical and thermal conductivity are discussed using Group 1, Group 2, and Group 13 metals, including real-world deviations from simple models (for example, gallium). Comparisons with ionic, molecular, and covalent network solids help students clearly distinguish why metals behave differently.

Practical applications are embedded throughout, including the use of metals in electrical wiring, cooking equipment, and heat exchangers. Environmental and societal links are also included, such as aluminium recycling and its significant energy savings, providing opportunities for discussion, CAS links, or investigations.

The lesson includes starter activities, clearly stated learning outcomes, structured explanations, real-world examples, practice questions, and answers. It is suitable for classroom teaching, consolidation, or independent study.

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

BUNDLE S2.3 The Metallic Model SL & HL Content (IBDP Chemistry)

This PowerPoint bundle covers IBDP Chemistry Topic S2.3: The Metallic Model (SL & HL), explaining metallic bonding, structure, properties and transition metals for first examination 2025. It provides a clear, sequenced approach to help students understand how the metallic model explains the behaviour of metals. The metallic model describes metals as a lattice of positive metal cations surrounded by a “sea” of delocalised electrons. These mobile electrons are responsible for key properties such as electrical conductivity, thermal conductivity, malleability and ductility. This bundle supports students in linking bonding and structure directly to observable properties and trends across the periodic table. This resource includes four fully editable PowerPoint (.pptx) lessons, designed for both SL and HL teaching: • Metallic bonding and structure, including the electron-sea model and lattice arrangement • Strength of metallic bonding, focusing on ionic charge, ionic radius and electron density • Physical properties and applications of metals, linking bonding to conductivity, malleability and real-world uses • HL transition metals, including d-block characteristics, variable oxidation states and complex ion formation Each lesson includes: • Retrieval starters to activate prior knowledge • Clear definitions of key terms aligned to IB terminology • Step-by-step explanations of concepts and trends • Diagrams and models to support visual understanding • Practice questions with answers for consolidation The bundle is ideal for classroom delivery, revision, or flipped learning, and supports progression from core SL understanding to HL depth. It helps students develop strong conceptual links between bonding, structure and properties—essential for success in IB assessments. File types included: • 4 × Editable PowerPoint (.pptx) files Last updated: 2026 – includes improved sequencing, clearer explanations of bonding models, additional HL extension content, and enhanced practice questions aligned to IB assessment objectives.

BUNDLE S2.3 The Metallic Model SL Content (IBDP Chemistry)

This bundle of PowerPoints covers the Standard Level content of Topic 2.3 The Metallic Model for IBDP Chemistry (first examination 2025). It provides a clear, structured explanation of metallic bonding, metallic structure and the physical properties of metals, fully aligned to the updated syllabus. The metallic model describes metals as a lattice of positive metal cations held together by a “sea” of delocalised valence electrons. This electrostatic attraction between cations and mobile electrons explains key metallic properties such as electrical conductivity, thermal conductivity, malleability and ductility. Across the lessons, students build understanding from the basic definition of metallic bonding to explaining trends in melting point, hardness and conductivity using ionic radius, ionic charge and electron density. The bundle includes: • Metallic Bonding and Structure – definition of metallic bonding, crystalline lattices, the free electron model, comparison with ionic and covalent bonding • Strength of the Metallic Bond – factors affecting bond strength, trends down groups and across periods, links to melting point and hardness • Physical Properties and Applications of Metals – malleability, ductility, electrical and thermal conductivity, real-world applications and data use Each PowerPoint includes starter activities, key word definitions, clear explanations, diagrams, mini-whiteboard checks and structured practice questions with answers. There are also links to real data (e.g. NIST alloy database) and contextual examples such as aluminium recycling to support applications and CAS-style discussion. This resource is ideal for teaching, consolidation or revision of SL metallic bonding. File types included: Multiple PowerPoint files (.pptx) Last updated: January 2026 – improved sequencing, clarified exam wording and strengthened links between structure and property explanations.
