Atom, Orbitals, and Quantum Numbers (s/p/d/f)
Build electron configurations and test orbital filling with quantum numbers.
Water Mixing Dynamics
Mix two solutions and observe concentration leveling over time: C_final, t_mix, diffusion, and stirring.
All Simulations
Chemical Bonding and Molecular Geometry: Lewis + VSEPR
Build Lewis structures, compare VSEPR shapes, and estimate molecular polarity.
Chemical Equilibrium: Le Chatelier Principle
Change concentration, volume, and temperature and predict shifts using Q and K.
