VSEPR Molecular Geometry
Explore 3D molecular geometries for common electron-domain configurations. Rotate and inspect tetrahedral, trigonal planar, linear, octahedral, and bent structures. Understand how lone pairs distort ideal bond angles.
Atomic Orbital Shapes
Explore 3D probability cloud visualizations of s, p, and d atomic orbitals. Toggle between 1s, 2s, 2px/y/z, 3dz², 3dxy, and 3dx²-y² orbitals. Adjust particle count, opacity, and size to reveal electron density patterns. Quantum numbers update automatically.
Periodic Trends Explorer
Interactive heatmap of the periodic table showing ionization energy, electronegativity, atomic radius, and electron affinity trends. Hover any element to see its exact values and electron configuration. Toggle between four properties and observe the patterns across periods and groups.
Reaction Energy Diagrams
Build interactive reaction energy diagrams with adjustable activation energy, ΔH, and catalyst effect. Switch between exothermic and endothermic reactions, watch the transition state and energy levels update live, and animate a molecule traveling along the reaction pathway.
Gas Laws
Interactive gas law explorer with five tabs: Boyle's Law (PV = const), Charles's Law (V∝T), Gay-Lussac's Law (P∝T), Ideal Gas Law (PV=nRT), and Dalton's Law (partial pressures pie chart). Each tab shows an animated particle container, a live graph (hyperbola/linear/PV), and computed result values.
Ionic vs Covalent Bonding
Compare ionic and covalent bond formation side by side. Four tabs: Ionic (electron transfer animation for NaCl, MgO), Covalent (shared electron clouds for H₂, O₂, N₂), Polar Covalent (dipole arrows for H₂O, HCl), and Properties Comparison table. An electronegativity difference bar chart highlights ΔEN cutoffs at 0.4 and 1.7.
Intermolecular Forces
Explore London dispersion, dipole-dipole, and hydrogen bonding through animated particle simulations. Flickering electron clouds show temporary dipoles for London forces; polar arrows show permanent dipoles; dashed H-bond lines connect water molecules. A boiling point bar chart at the bottom compares H₂O, HF, NH₃, H₂S, HCl, and CH₄ to illustrate IMF effects on BP.
Electron Configuration
Click any element (Z=1–36) to see its animated Bohr-model atom with color-coded s/p/d shells, orbital-box diagram applying Aufbau, Pauli exclusion, and Hund's rules, and full spdf notation. Stat card shows valence electrons, period, group, and configuration. Includes special cases Cr (Z=24) and Cu (Z=29).
