Periodic Table

Periodic Table 2026 is the most complete chemistry learning app — built for students who want to actually learn, not just look things up. INTERACTIVE PERIODIC TABLE • Explore all 118 elements with pinch-to-zoom and pan • Color the table by category, phase, electronegativity, density, or melting point • Tap any element to view detailed properties, history, uses, and interesting facts • Beautiful Bohr model atom animation for every element DEEP ELEMENT DETAILS Every element page includes: • 23+ physical and chemical properties • Real-world uses and applications • Discovery history • Interesting facts you won’t find in textbooks • Common compounds and safety information • Electron configuration with an animated Bohr model CHEMISTRY CALCULATORS • Molar Mass Calculator — enter any formula (H₂O, Ca(OH)₂, C₆H₁₂O₆) using a custom chemistry keyboard • Equation Balancer — balance chemical equations with step-by-step explanations • Unit Converter — temperature, pressure, mass, volume, concentration, energy • Dilution Calculator — solve C₁V₁ = C₂V₂ for any unknown variable • Solubility Chart — interactive grid of common ion solubility QUIZ & GAMIFICATION • 3 difficulty levels: easy, medium, hard • 6 question types, including electron configuration and atomic mass • Daily streak tracking with streak freeze protection • XP system with 6 levels: Beginner → Student → Enthusiast → Chemist → Professor → Nobel Laureate • 12 unlockable achievements and badges LEARNING GAMES • Flashcards with the SM-2 spaced repetition algorithm — scientifically proven to improve memory • Element Match — a memory game matching elements to their symbols • Speed Run — name as many elements as you can in 60 seconds CHEMISTRY REFERENCE • Physical constants (Avogadro’s number, gas constant, Planck’s constant, and more) • Polyatomic ions table (18 common ions) • Activity series (metals ranked by reactivity) • Common chemistry formulas (ideal gas law, pH, Gibbs free energy, Nernst equation) COMPARE ELEMENTS Select any two elements and compare their properties side by side — including atomic mass, density, melting point, electronegativity, and more. WORKS OFFLINE All element data, calculators, quizzes, and games work without an internet connection — perfect for studying anywhere.
