A web app for learning the periodic table

Pick your elements. Then get quizzed on them.

Choose how many elements to study, then quiz yourself on their symbols, names, or atomic numbers.

How it works

  1. 1

    Pick and shuffle

    Choose 6, 12, 18, or 24 elements, and optionally a category like noble gases or halogens. Each card shows the symbol, name, atomic number, and category.

  2. 2

    Choose your quiz

    Quiz yourself on symbols, names, atomic numbers, or any mix. Type your answer and see right away if it was correct.

  3. 3

    Skip and come back

    Stuck on one? Skip it. It moves to the back of the line, so you still answer every question.

What’s inside

  • 118 elements

    The full table, from hydrogen to oganesson.

  • Your set, your quiz

    Choose how many elements, which categories, and which kinds of questions. Shuffle without repeats until you have seen all 118.

  • Colors that teach

    Every card is colored by its category, so you start to see how the table is organized.

  • Built for phones

    Big buttons and a full-screen quiz, so it works well on a small screen. No sign-up needed.

Every element, color-coded

  • alkali metal
  • alkaline earth metal
  • transition metal
  • post-transition metal
  • metalloid
  • nonmetal
  • halogen
  • noble gas
  • lanthanoid
  • actinoid

The card for each element shows its category in the same color, so patterns in the table start to stick.

Shuffle. Quiz. Repeat.
