Chemistry — quantum mechanics applied, the periodic table
chemistry
The world of substances, standing on the physics region. Chemistry is the Schrodinger equation for electrons around nuclei, plus Pauli exclusion, plus electromagnetism; the periodic table falls out of the quantum shells, thermodynamics decides which reactions run, and conservation of atoms makes every equation balance. Four pillars rest on quantum mechanics (the periodic table), Maxwell (the bond), thermodynamics (Delta G), and Noether (conservation). The stick (stick_chemistry_quantum_mechanics_applied_the_periodic_table) seals the shell capacity and water's molar mass; reactions, Gibbs and pH are cited from the chemistry stick (tools/seed_chemistry.py).
