Can I quiz the first 20 elements or choose another range?

Choose the first 20, 36 or 54 elements, all 118 from hydrogen to oganesson, or Custom range. For the first 10, enter 1 in From atomic number and 10 in To atomic number. Choose Every element once to cover your whole set; other lengths ask up to 10, 20 or 50 questions, without repeats.

Can a teacher share a quiz on only some elements?

Yes. Set the elements, question direction and length, then press Share this set and copy the link. Anyone who opens it gets those settings and a fresh round. A link shares the practice setup, not your answers or saved progress.

Does capitalization matter for element symbols?

Yes, for symbols. A symbol is a capital letter, followed by a small one when there are two, so Ac is right for actinium while AC and ac are marked wrong, with a note showing the right case. Names count in any case, so Actinium, actinium and ACTINIUM are all right.

Is it aluminum or aluminium, cesium or caesium?

Both count when you type them. The table lists aluminium, caesium and sulfur, as the Wikidata snapshot spells them, and typed answers also accept aluminum, cesium and sulphur. Questions that name one of these elements give both spellings, and a multiple-choice round never offers the other spelling as a wrong choice.

Can I quiz element symbols, names or atomic numbers?

Use Name to symbol to recall chemical symbols, Symbol to name to name the elements, and Name to number or Symbol to number to recall atomic numbers. All six directions are available individually, and Mixed chooses among them for each question. Pick Typed for recall and spelling practice or Multiple choice for four answer options. The timer can be off, a stopwatch, or a 1, 3 or 5 minute limit.

Can I print a periodic table quiz worksheet with answers or save a PDF?

Print questions opens the current round as a question sheet, and Print key opens its answer key separately. Multiple-choice sheets include options lettered a to d, with the correct letter in the key. Open Preview the printable questions and answer key under Review to inspect both sheets. If your print dialog offers Save as PDF, use it to save each sheet as a PDF.

How can I use the quiz as a periodic table memorization game?

Try a short round in one direction, check each answer and compare your score on a new round. After finishing, use the practice button in the completed round to retry the elements you missed. Reveal shows an answer and marks it missed, so it remains in your review set.

Is my progress saved?

In this browser only. The page keeps your settings, the round in progress, how many rounds you have finished, your last score, which elements you have missed most and how many questions you answered each day, and a button asks every element you have missed before again. Clear progress forgets the rounds and misses; the Start over button at the top of the page forgets everything the page saved. Nothing you type is sent anywhere.

Is the periodic table quiz free and usable in a browser?

Yes. The quiz and its study controls are free to use without an account or an installation. Use a current browser on a phone, tablet or computer. Once loaded, the element questions work offline; printing and saving a PDF depend on the browser and device.

Sources

Wikidata snapshot, 21 September 2026. Element names, symbols and atomic numbers come from Wikidata, released under CC0 1.0, retrieved with a query to the Wikidata Query Service and bundled with this page, so it makes no request for them. Every number and symbol pair matches PubChem. The questions, choices and sheets are original to this page.

Source files, served from this site: element facts (JSON), query result (JSON), the query, licence notice.

Type the answer and press Enter to check it, then Enter again for the next question. In a multiple-choice round, keys 1 to 4 pick an answer while a choice has focus, as the first one does after Next. Full-width letters and digits are read as plain ones.

Accuracy. Names, symbols and atomic numbers for all 118 elements come from a Wikidata snapshot dated 21 September 2026 (CC0), with every number and symbol cross-checked against PubChem; names are spelled as that snapshot spells them, such as aluminium and caesium, and typed answers also accept aluminum, cesium and sulphur. The questions are original and cover element identities only: no masses, properties or handling information. A score counts right answers in this round and is not a grade or a level.
