Periodic Table & 3D Chemistry

Explore the elegance of chemistry in the palm of your hand! Periodic Table & 3D Chemistry is a comprehensive, interactive science laboratory designed for students, educators, and chemistry enthusiasts.

100% offline-ready, completely ad-free, featuring all 118 IUPAC elements with laboratory-grade interactive visual simulations.

🌟 CORE HIGHLIGHTS:

1. INTERACTIVE 18-COLUMN PERIODIC TABLE
• Complete 118 IUPAC chemical elements with verified scientific data.
• Interactive Lenses: filter by Category (Alkali Metals, Transition Metals, Noble Gases, Lanthanides, Actinides), Discovery Timeline, Electron Blocks (s, p, d, f), and Origin / Radioactivity.
• Interactive temperature slider (Kelvin & Celsius) to observe real-time state transitions (solid, liquid, gas).
• Switch smoothly between the classic 18-column grid and quick-search Card List view.

2. 3D BOHR ATOM VISUALIZER
• Interactive 3D WebGL atomic simulation: inspect orbiting electrons, electron shells (K through Q), protons, and neutrons.
• Live visualization of cation and anion ionization states.

3. QUANTUM ORBITAL LABORATORY (SCHRÖDINGER EQUATION)
• Realistic 3D electron probability clouds derived from quantum mechanical wave equations (1s, 2s, 2p, 3s, 3p, 3d, 4f).
• Cross-section slice controls and wave-function phase signs (ψ > 0 and ψ < 0).
• Subshell spin diagram illustrating the Aufbau principle, Pauli exclusion principle, and Hund's rule.

4. PERIODIC TRENDS & HEATMAP EXPLORER
• Live table heatmaps for Atomic Radius, First Ionization Energy, Electronegativity (Pauling Scale), Electron Affinity, Density, Melting Point, and Metallic Character.
• 3D Skyline graph for spatial visualization of element properties.

5. 3D MOLECULAR SYNTHESIS LAB
• Combine atomic elements to construct real chemical molecules (H₂O, CO₂, NaCl, etc.).
• Interactive ball-and-stick models with accurate bond geometries and stoichiometry calculations.

6. OPTICAL EMISSION SPECTRUM & 3D FLAME TEST LAB
• Interactive emission spectrograph showcasing atomic emission lines.
• Realistic 3D Bunsen burner flame test simulator for metal salts (Na, K, Cu, Sr, Ba) with Cobalt Blue glass filter.

7. SIDE-BY-SIDE ELEMENT COMPARISON
• Compare atomic structure, physical constants, electronegativity, isotopes, and discovery background side-by-side.

8. CHEMISTRY MASTERY QUIZ
• Test your skills across difficulty tiers: General, High School, and University.
• Score tracking and celebratory visual milestones.

🔒 PRIVACY & QUALITY GUARANTEE:
