Periodica 3D: Periodic Table

Explore the chemical elements like never before with Periodica 3D — the advanced, interactive 3D periodic table and chemistry reference lab designed for students, educators, and science enthusiasts.

🔬 KEY SCIENTIFIC FEATURES & MODULES:

• 118-ELEMENT INTERACTIVE PERIODIC TABLE:
Explore all 118 chemical elements in Standard IUPAC, Extended 32-column, and Block-based layouts. Features a thermodynamic slider to scrub temperatures from 0 K to 6,000 K and watch real-time solid, liquid, and gas state transitions.

• REAL-TIME 3D QUANTUM ORBITALS:
Visualize hydrogenic electron probability clouds and wavefunctions (s, p, d, and f subshells). Slice through orbitals with interactive cross-section planes to reveal inner radial nodes, lobes, and quantum state numbers (n, ℓ, m) with binding energies.

• DUAL CHEMICAL CLASSIFICATION:
Accurate scientific categorization including secondary classifications — notably Astatine (tagged as both Halogen & Metalloid) and Polonium, complete with relativistic callouts.

• 3,000+ NUCLEAR ISOTOPES & DECAY:
Investigate isotopic abundances and 6 radioactive decay pathways (Alpha, Beta-, Beta+, Electron Capture, Spontaneous Fission, and nucleon emission). Run live Monte Carlo simulations in a 100-atom stochastic particle chamber to visualize half-life decay.

• AUFBAU PRINCIPLE & SUBSHELL FILLING:
Interactive energy level diagrams (1s to 7p) governed by the Madelung rule, featuring real-time detection of transition metal anomalies (Chromium and Copper stability exceptions) with Hund's rule and Pauli spin indicators.

• 3D MOLECULAR COMPOUNDS:
Touch and freely rotate interactive ball-and-stick models for Caffeine, Water, Glucose, and complex organic compounds. Review stoichiometric elemental mass ratios and search millions of compounds via PubChem integration.

• CHEMICAL REACTION BALANCER:
Solve complex chemical equations instantly using a Gaussian elimination matrix engine, complete with real-time atom conservation verification and reaction classification.

• 3D CRYSTAL LATTICES:
Inspect 6 Bravais crystal unit cells (FCC, BCC, HCP, Diamond, Rock Salt) with dynamic Miller index crystallographic planes (100, 110, 111), theoretical densities, and atomic packing factors (APF).

• ELEMENT COMPARISON RADAR:
Compare two or three elements side-by-side on a normalized 6-axis radar chart analyzing Electronegativity, Ionization Energy, Atomic Radius, Density, and Melting Points.

• CHEMISTRY QUIZ LAB:
Reinforce learning with interactive quizzes across element names, chemical symbols, atomic numbers, groups, and orbital blocks with real-time accuracy tracking.

✨ 100% OFFLINE & PRIVACY-FIRST:
• Operates completely offline with zero mandatory internet connection.
• No account registration, no login walls, and no personal data collection.
• Zero in-app banner ads.
• Compliant with COPPA and student privacy guidelines.

📚 SCIENTIFIC STANDARDS:
All atomic constants and chemical parameters are compiled from IUPAC, NIST, and peer-reviewed scientific literature.
