About this app

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.

DARK MODE

Full dark theme support that’s easy on the eyes during late-night study sessions.

HOME SCREEN WIDGET

The “Element of the Day” widget shows a new element every day right on your home screen. Tap to explore.
