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

BUNDLE R1.4 Entropy and Spontaneity HL Only Content (IBDP Chemistry)
This bundle of 3 PowerPoints covers IBDP Chemistry HL R1.4 Entropy and Spontaneity for first examination 2025, including entropy changes, Gibbs energy, spontaneity and the link between Gibbs energy and equilibrium. It provides a clear, carefully sequenced set of lessons that helps students move from core thermodynamic ideas to the higher-level calculations and interpretations required for IB exam success. Entropy and spontaneity are central ideas in thermodynamics. Entropy is a measure of disord

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

S3.2 Homologous Series (IBDP Chemistry)
This PowerPoint lesson introduces homologous series in organic chemistry for IBDP Chemistry (first examination 2025) and explains how organic compounds are grouped based on their functional group and structure. It helps students understand patterns in organic molecules and predict trends in physical and chemical properties. A homologous series is a family of organic compounds that share the same functional group and general formula. Members of the same series have similar chemical properties but

S3.2 Infrared Spectroscopy, HL (IBDP Chemistry)
This PowerPoint lesson covers infrared (IR) spectroscopy for IBDP Chemistry HL (first examination 2025), focusing on identifying functional groups and interpreting spectra. It provides a clear, structured approach to analysing IR data and linking absorption peaks to molecular structure. Infrared spectroscopy is an analytical technique used to identify the types of bonds present in a compound based on how they absorb infrared radiation. Chemical bonds vibrate at specific frequencies, and when IR

S3.1 Structure of the Periodic Table (IBDP Chemistry)
This PowerPoint lesson introduces the structure of the periodic table, helping IBDP Chemistry students understand how elements are organised and why patterns in properties occur. Designed for first assessment 2025, it builds a clear foundation in classification, electron configuration, and periodic trends required for exam success. The periodic table arranges elements by increasing atomic number into groups (columns) and periods (rows), allowing patterns in chemical and physical properties to be

S3.1 Electrons and the Periodic Table (IBDP Chemistry)
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
