Topic C2.2: Bonding (OCR Gateway A GCSE Combined Science)

This bundle of 10 lessons covers the majority of the content in the sub-topic C2.2 (Bonding) of the OCR Gateway A GCSE Combined Science specification. The topics and specification points covered within these lessons include:

• Describe metals and non-metals and explain the differences between them
• Formation of ions
• Common reactions of metals
• Explain how the atomic structure of metals and non-metals relates to their position in the Periodic Table
• Explain how electron arrangement is related to group and period number
• Describe and compare the nature and arrangement of chemical bonds in ionic compounds, simple molecules, giant covalent structures, polymers and metals
• Explain chemical bonding in terms of electrostatic forces and as the transfer or sharing of electrons
• Construct dot and cross diagrams for simple covalent structures and ionic substances

All of these lesson presentations and accompanying resources are detailed and engaging and contain regular progress checks to allow the students to constantly assess their understanding.
