  1. 01

    Matter, measurement, and atomic structure

    • Classify matter and measurements.
    • Use isotopes, atomic models, and electron configuration.

    Practice: Write an atomic-structure explanation for a periodic trend.

  2. 02

    Bonding and molecular structure

    • Compare ionic, covalent, and metallic bonding.
    • Use Lewis structures, VSEPR, polarity, and intermolecular forces.

    Practice: Predict properties from structure and justify with particle-level reasoning.

  3. 03

    Stoichiometry and reactions

    • Balance equations and use mole ratios.
    • Classify precipitation, acid-base, gas-forming, and redox reactions.

    Practice: Solve a limiting-reactant lab-style problem with units at every step.

  4. 04

    Solutions, gases, and mixtures

    • Use molarity, dilution, gas laws, and partial pressure.
    • Explain solution formation and separation methods.

    Practice: Design a dilution and calculate expected concentration.
