简介
Khan Academy Chemistry Curriculum Overview
This page serves as an archive for the Khan Academy Chemistry course, covering fundamental and advanced topics in chemical science.
- 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.
- Bonding & Molecular Geometry:
- Lewis dot structures and formal charges.
- VSEPR theory (molecular geometry for 2–6 electron clouds).
- Resonance, octet rule exceptions, and molecular polarity.
- Chemical Reactions & Stoichiometry:
- Balancing equations and stoichiometry.
- Molecular composition and ideal gas equations.
- Oxidation-reduction (redox) reactions and balancing in acidic/basic solutions.
- States of Matter & Intermolecular Forces:
- Kinetic molecular theory, phase diagrams, and vapor pressure.
- Specific heat, latent heat, and phase changes.
- Intermolecular forces (London dispersion, dipole-dipole, hydrogen bonding, ion-dipole).
- Solubility, surface tension, and capillary action.
- Acids, Bases, & Equilibrium:
- Acid-base equilibria and buffer solutions.
- Comprehensive titration methods (strong/weak acids and bases, redox titrations).
- Electrochemistry & Thermodynamics:
- Galvanic cells and standard cell potentials.
- Cell potentials under nonstandard conditions.
- Chemical Kinetics:
- Rate laws and reaction concentrations over time.
- Zero, first, and second-order reactions (including calculus-based derivations).
- Half-life calculations and radioactive decay.
