Chemistry

Everything around us is made up of chemicals! Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

Calling great explainers of the world! Help us answer frequently asked chemistry questions by writing clear, deep, engaging explanations. Your explanation may even be selected for an article on Khan Academy (with full credit to you)!

Atoms, molecules, and ions

Atomic structure, atomic numbers, atomic mass, moles, ions (eventually), compounds (eventually)

Chemical reactions and stoichiometry

We are now going to delve into the heart of chemistry. We learn ways of representing chemical molecules and how molecules react. To do this, we'll even think about "how many" of a molecule we have using a quantity called a "mole".

Electronic structure of atoms

Bohr model, absorption, emission spectrum, quantum numbers, electron configurations

Periodic table

Classification of elements, atomic radii, ionic radii, ionization energy, electron affinity

Chemical bonds

Ionic bonds, metallic bonds, covalent bonds, electronegativity, Lewis dot structures, VSEPR, hybridization

Gases and kinetic molecular theory

Gas laws (eventually), ideal gas equation, Dalton's law (eventually), kinetic molecular theory (eventually)

States of matter and intermolecular forces

Intermolecular forces, liquids, solids, phase changes

Chemical equilibrium

Equilibrium constant, heterogeneous equilibria, le Chatelier's principle

Acids and bases

Definitions, pH, strong and weak acids and bases, acid-base equilibrium, salt solutions

Applications of acid-base equilibria and solubility equilibria

Titrations, buffers, solubility equilibria, and the common-ion effect

Thermodynamics

Thermodynamics is the study of heat, "thermo," and work, "dynamics." We will be learning about energy transfer during chemical and physical changes, and how we can predict what kind of changes will occur. Concepts covered in this tutorial include the laws of thermodynamics, internal energy, heat, work, PV diagrams, enthalpy, Hess's law, entropy, and Gibbs free energy.

Redox reactions and electrochemistry

Oxidation states (numbers), oxidation-reduction (redox) reactions, galvanic/voltaic Cells, electrolytic cells

Kinetics

Reaction rates, rate laws, Arrhenius equation, catalysts

Nuclear chemistry

Nuclear reactions, nuclear stability, radioactive decay

Ask a chemist! (Archived)

Hi, my name is Yuki and I get really excited about chemistry. Do you have a question or comment that might be related to chemistry? Ask your question between July 30 and August 2, and I will try my best to answer it. Please feel free to join in the discussion and answer some questions too!
