Explore the foundations of chemistry: structure, bonding, reactions, and equilibrium.
This section introduces the foundations of chemistry: how atoms, electrons, and energy combine to explain matter and change. By the end, you’ll be able to reason about chemistry conceptually through patterns, practice, and real examples.
Pick a concept to start. Each one can have intuition, math, practice, and applications.
Structure, orbitals, and why electrons drive everything.
Start here →Ionic, covalent, metallic—how atoms stick together.
Start here →Thermo + kinetics: what can happen and how fast.
Start here →Reversibility, Le Châtelier, and chemical balance.
Start here →pH, buffers, and proton/electron bookkeeping.
Start here →Step-by-step reaction pathways (organic + beyond).
Start here →Explore a real-world theme that ties multiple concepts together.
How bonding and structure create material properties.
Explore →Why reactions happen (or don’t) in real systems.
Explore →Chemistry behind drugs, diagnostics, and design.
Explore →Air chemistry, oceans, carbon, and pathways to change.
