What is in this deck
With this deck you learn all 118 elements of the periodic table with symbol and atomic number, from hydrogen to oganesson.
Sb is antimony, W is tungsten, Hg is mercury. For eleven elements the symbol has nothing to do with the English name and everything with the Latin one, and those eleven are exactly where people stumble.
This deck asks all 118 elements by their symbol. Every card carries the atomic number, and where the symbol comes from Latin, the word is given: stibium, hydrargyrum, plumbum.
Atomic numbers and symbols are taken from Wikidata, which holds them in the public domain.
The categories decide what comes up: start with “Heavy elements” alone and add the rest when you are ready.

Learning with Qardbox
You see a card, you think, you turn it over and say whether you knew it. A round asks nothing more of you, and how the app works out the next date from that is on the page about FSRS-6.
What sits comes back less often, what wobbles comes back soon. You set a daily goal, and when nothing is due the app tells you exactly that instead of inventing work for you. How a round goes is shown on the learning page.
Everything stays on your device. No account, no sign-up, no ads. After the purchase the deck sits in your library like any other subject and can be studied, reordered and extended just like your own.
What it costs, and what it doesn’t
Qardbox itself costs nothing, and it stays that way. Every function is there from the start, with no subscription, no ads and no tiers; what that rests on is on the page about what it costs.
Your own cards stay unlimited, and decks from friends or from the family you read in without a limit, from a file as well. You do not need this deck in order to learn with Qardbox.
This deck costs nothing. Its 118 cards are checked and save you the work you would otherwise have.
