## What is (Open Source) Periodic Table?

A clean, free periodic table for chemistry students, teachers, and curious people.

Explore all 118 elements in an interactive table, then tap into detailed element cards with atomic, physical, discovery, and isotope data. Switch color modes to see trends across the table, search by name or symbol, compare properties, and use practical tools when homework or curiosity sends you down a chemistry rabbit hole.

FEATURES

Interactive Periodic Table
Pinch, pan, zoom, and tap through the full periodic table with category colors and property heatmaps.

Element Details
See atomic mass, density, melting point, boiling point, electronegativity, radius, electron shells, discovery facts, isotopes, and more.

Search and Lists
Find elements quickly by name, symbol, or atomic number.

Isotopes Browser
Browse thousands of nuclides with half-life, decay, abundance, and nuclear data.

Molar Mass Calculator
Parse formulas with nested groups and hydrates, then see the element-by-element mass breakdown.

Chemistry Tools
Balance equations, review common reactions, inspect trends, and use reference tables for ions, solubility, constants, and organic series.

Mini Academy and Dictionary
Learn core chemistry ideas with compact lessons, glossary entries, and quick checks.
