Become unbeatable on the entire periodic table! Elemlearn is the perfect app to learn and review all 118 chemical elements - their names, their symbols, and the families they belong to - in a fun, ad-free way. Two game modes Quiz yourself either way: Element → Symbol or Symbol → Element. Switch anytime to challenge your memory from both angles. Smart review The app automatically spots the elements you know least and brings them back more often, with tricky look-alike options (like Silicon vs Selenium, or Sodium vs Sulfur) to sharpen your memory and avoid confusion. Bohr diagrams Every answer reveals the element's electron shells, atomic number, atomic mass and family - so you learn the real chemistry, not just the letters. Track your progress Detailed stats, a daily streak, and mastery family by family, so you always know exactly where you stand. Six languages Interface in English, French, Spanish, Portuguese, Italian and German.
