These IB Chemistry SL notes provide a complete and organized review of Topics 1 through 8 from the Standard Level syllabus. Spanning 45 pages, this resource simplifies complex concepts into digestible summaries with equations, definitions, diagrams, and clear examples aligned with IB assessment standards.
Covered Topics:
-
Topic 1: Stoichiometric Relationships
Understanding chemical formulas, the mole concept, empirical and molecular formulas, molar volume, and stoichiometric calculations including limiting reagents and theoretical yield. -
Topic 2: Atomic Structure
Subatomic particles, isotope notation, electron configurations (Aufbau principle, Hund’s rule, and Pauli exclusion), emission spectra, and evidence for atomic models. -
Topic 3: Periodicity
Trends in atomic radius, ionization energy, electronegativity, melting point, metallic/non-metallic behavior, and understanding the periodic table layout based on electronic structure. -
Topic 4: Chemical Bonding and Structure
Ionic, covalent, metallic bonding, Lewis structures, VSEPR theory, resonance, formal charge, hybridization, and molecular polarity. -
Topic 5: Energetics/Thermochemistry
Exothermic and endothermic reactions, enthalpy change, calorimetry, Hess’s Law, bond enthalpies, and application to reaction energetics. -
Topic 6: Chemical Kinetics
Collision theory, Maxwell-Boltzmann distribution, factors affecting reaction rate, reaction mechanisms, and use of concentration-time graphs. -
Topic 7: Equilibrium
Reversible reactions, dynamic equilibrium, Le Chatelier’s Principle, equilibrium constant (Kc), and factors influencing shifts in equilibrium. -
Topic 8: Acids and Bases
Definitions (Arrhenius, Brønsted-Lowry), properties of acids and bases, pH calculations, strong vs weak acids/bases, and neutralization reactions.
Each section is presented in a format that aligns with IB command terms and is tailored for quick revision and exam confidence. Whether you’re preparing for your end-of-year papers or working through the IB’s internal assessments (IAs), these notes support both conceptual understanding and memorization of required definitions and formulas.
Compiled by a high-achieving IB student, this 45-page summary provides a complete breakdown of the SL Chemistry core. It reflects key syllabus points and is suited for both self-study and group review sessions.
