S3.1 Discontinuities in Ionisation Energy, HL (IBDP Chemistry)
This PowerPoint lesson explains discontinuities in first ionisation energy for IBDP Chemistry HL (first examination 2025), helping students understand deviations from periodic trends. It provides a clear, structured explanation of how these discontinuities give evidence for sublevels and electron pairing. Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms to form one mole of gaseous 1+ ions. Across a period, first ionisation energy generally i

S3.1 Metallic and Non-Metallic Continuum (IBDP Chemistry)
This PowerPoint lesson explores the metallic and non-metallic continuum, showing how bonding and oxide behaviour change smoothly across Period 3. Designed for IBDP Chemistry (first assessment 2025), it helps students connect electronegativity, bonding type, and acid–base properties to observable chemical trends. Chemical bonding and element behaviour exist on a spectrum rather than in rigid categories. This lesson develops the idea of a continuum from metallic to ionic to covalent bonding using

R1.4 Entropy, HL (IBDP Chemistry)
This PowerPoint lesson covers entropy and disorder for IBDP Chemistry (first examination 2025), helping students understand energy dispersal and predict entropy changes in physical and chemical processes. It provides a clear, structured approach to both conceptual understanding and calculation of standard entropy changes. Entropy (S) is a measure of the disorder or randomness of particles in a system, as well as how energy is distributed. Systems with higher entropy have particles that are more
