What is in this deck
With this deck you learn the numbers behind 51 chemical elements: state of matter, density, melting point and the year of discovery.
Tungsten melts at 3422 °C, helium boils at minus 269, osmium weighs 22 grams per cubic centimetre. Numbers you want in your head and don't have.
Melting point, boiling point, density and year of discovery for 51 elements, plus the records and the two elements that are liquid at room temperature.
The values come from the periodic table of PubChem, the public data collection of the US National Institutes of Health. The record cards are recalculated against that same table at build time.
The categories decide what comes up: start with “Density” alone and add the rest when you are ready.
What you learn
- Melting and boiling points of the key elements

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 222 cards are checked and save you the work you would otherwise have.
