Atom, Orbitals, and Quantum Numbers (s/p/d/f)
Build electron configurations and test orbital filling with quantum numbers.
Solutions and Dilutions: C₁V₁ = C₂V₂
Prepare and dilute solutions, apply C1V1 = C2V2, and verify concentrations.
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.
