01 Foundational
Atomic structure and bonding
Starting from periodic trends, electron configuration, ionization energy and chemical bonding appear as different faces of one set of rules for electronic structure.
2 implemented0 framework pages to implement
02 Intermediate
Crystals and solids
Bring macroscopic properties back to the lattice scale: packing, diffraction, band structure and solid solutions all follow from the way atoms are arranged.

03 Intermediate
Chemical thermodynamics and kinetics
Two rulers for a reaction: whether it can happen, whether it releases heat, how fast it goes, and how a catalyst changes only the rate.

04 Intermediate
Organic chemistry
Draw a mechanism as curved arrows: where the electrons come from and where they go decides the product, the stereochemistry and the rate.
