ChemLex turns chemistry into a language students can truly understand. Instead of memorizing isolated facts, they learn how science is built — from words to symbols, all the way to real chemical formulas.
No signup, no download -- just the ChemLex mechanism, live in your browser.
Chemistry is a language — and ChemLex teaches students to read it, instead of memorizing it by heart.
Here's a real screen from ChemLex Encode, exactly as is — an ordinary sentence, turned into a clickable, color-coded periodic table, in one click.
"Serious, Classic, New and Funny" — decoded live in ChemLex Encode.
Every module has a clear purpose, powered by the same chemical decomposition engine.
Words sorted by theme — pure sciences, life and society, sport and more — to discover scientific language in context.

Students learn to decode scientific vocabulary by breaking it down into chemical symbols — they stop memorizing and start understanding.
Students learn to read and build real chemical formulas — recognize a compound, and build its formula element by element.
The language of reactions: balancing equations, IUPAC nomenclature, stoichiometry, ions and oxidation states, organic compounds and functional groups.
