Atom, Orbitals, and Quantum Numbers (s/p/d/f)
Build electron configurations and test orbital filling with quantum numbers.
Reaction Rate and Catalyst
Test how temperature, concentration, surface area, and catalyst change reaction rate.
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.
