Learning the periodic table from a wall chart fails for a simple reason: the chart shows you everything at once, so you keep re-reading the twenty symbols you already know to reach the ones you don't. This deck puts each element on its own card — the symbol asks the question on the front, the name and its category answer it on the back. Every card is tagged by block, so you can run just the transition metals, just the lanthanides, or just the main group instead of the whole table. Import it and the deck joins your spaced-repetition schedule. Elements you know stretch out and drop out of sight; the ones that keep slipping come back until they stop slipping. What goes down is the number of symbols you still can't place — not the time it takes to scan past 118 cards you mostly can.

What happens when you add it

  1. 1

    The button opens Memly and the whole deck lands in your account.

  2. 2

    Each card gets its own schedule, based on how well you actually recall it.

  3. 3

    They are your cards afterwards — rewrite, delete or reorganize them freely.

Frequently asked

Can I import the whole deck on the free plan?

Yes. Importing a saved deck runs no new AI generation and does not use your AI allowance, so the free plan imports every card. You can study, edit and delete them afterwards.

Will importing it twice create duplicates?

No. Cards you already have are skipped and only cards added in a revision come through. Including re-imports after deleting it, one official deck can be imported three times per account.

Does it work on the web and in the mobile app?

Yes. The deck is added to your account, so the web app, the iOS app and the Android app all show the same cards and the same progress.

Can I edit the cards after importing?

Yes. Once imported they are your cards: edit either side, delete the ones you do not need, retag them, or move them into another deck.

What is on each card?

The symbol asks the question on the front; the name and its category answer it on the back. The 118 cards are tagged 50 main-group, 38 transition metals, 15 lanthanides and 15 actinides, so each block can be drilled on its own.

Which way round should I study it?

The card shows the symbol and asks for everything else, because that is the direction reading a formula demands. If you want name-to-symbol as well, edit a card and swap the sides, or duplicate the deck and swap them in bulk — both directions are yours once the deck is in your account.

Compiled 2026-08-17 from the standard element names, symbols and atomic numbers. Every card is written by Memly. Uses are the representative application named in introductory courses, not handling guidance: several of these elements are toxic or radioactive, and nothing here is a safety instruction. Elements 99 and above are marked research only rather than given an invented application.
