Khan Academy Chemistry Curriculum Overview

This archive contains a comprehensive collection of instructional materials covering core chemistry topics, ranging from atomic structure to advanced kinetics.

  • Atomic Structure & Periodic Table:
    • Quantum numbers, orbitals, and electron configurations.
    • Periodic trends (atomic radius, ionization energy, electron affinity, electronegativity, and metallic nature).
    • Coulomb’s law applications.
  • Chemical Bonding & Molecular Geometry:
    • Lewis dot structures and formal charges.
    • VSEPR theory (2 to 6 electron clouds).
    • Resonance, octet rule exceptions, and molecular polarity.
  • States of Matter & Intermolecular Forces:
    • Kinetic molecular theory, phase diagrams, and vapor pressure.
    • Specific heat, latent heat, and state changes.
    • Intermolecular forces: London dispersion, dipole-dipole, hydrogen bonding, and ion-dipole.
    • Solids, liquids, gases, and particulate models.
  • Chemical Reactions & Stoichiometry:
    • Balancing equations, stoichiometry, and molecular composition.
    • Ideal gas equations.
    • Oxidation-reduction (redox) reactions, including balancing in acidic/basic solutions and redox titrations.
  • Acids, Bases, & Equilibria:
    • Acid-base equilibria, pH, and buffer solutions.
    • Comprehensive titration coverage (strong/weak acids and bases, titration curves, and indicators).
  • Electrochemistry & Thermodynamics:
    • Galvanic cells and standard cell potentials.
    • Cell potentials under nonstandard conditions.
  • Reaction Kinetics:
    • Rate laws and reaction concentrations over time.
    • Zero, first, and second-order reactions (including calculus-based derivations).
    • Half-life calculations and radioactive decay kinetics.
