🎴Periodic Table Quiz - Practise Element Symbols, Names, Positions and Groups
The fastest way to learn the periodic table is to test yourself repeatedly and spend extra time on the elements you get wrong. This quiz offers eight drills: symbol to name (Fe → iron), name to symbol (sodium → Na; a wrong capital such as co is accepted but corrected to Co), clicking the element's position on a blank table, atomic number in both directions (element 26 is Fe), group and period (chlorine is in group 17, period 3), common oxidation states (iron is +2 and +3), filling in the whole table in order, and a flip-card drill for the first 20 elements with a recital check. You can limit questions to the first 20 or 36 elements, the main-group elements, all 118 or a custom set you pick on the table, and answer by multiple choice or by typing; common spellings such as aluminum/aluminium, sulphur/sulfur and cesium/caesium are all accepted. A 60-second challenge keeps a best score for each setting. Every answer updates that element's mastery score, and questions are weighted towards the elements you miss, much like spaced repetition. A heat map of the periodic table shows each element from red (weak) to green (strong) and lists your most-missed elements. Everything is stored only in your browser.

How to use Periodic Table Quiz
- 1Pick a drill: symbol → name, name → symbol, find it on the table, atomic number, group & period, oxidation state, fill the table or the first 20
- 2Choose the scope (first 20, first 36, main-group, all 118 or a custom set), multiple choice or typing, and optionally the 60-second challenge
- 3Answer and get instant feedback, then check the heat map and keep drilling the elements you find hardest
FAQ
- What is the best way to memorise the periodic table?
- Learn it in chunks and test yourself often. Start with the first 20 elements, hydrogen to calcium, until you can recite them in order, then extend to 36 (through krypton) and to the main-group elements. Mix the drills: writing symbols from names, naming symbols and placing elements on a blank table each strengthen a different link. This quiz tracks every element and serves the ones you miss more often, so practice time goes where it is needed.
- Are American and British spellings accepted?
- Yes. The site uses the IUPAC spellings aluminium, sulfur and caesium, but typed answers of aluminum, sulphur and cesium are also marked correct. Answers ignore upper and lower case for names. For symbols, case matters in chemistry (Co is cobalt, CO is carbon monoxide), so a symbol typed in the wrong case is accepted with a reminder of the correct form.
- How are groups numbered?
- Groups are numbered 1 to 18 following the current IUPAC convention: group 1 is the alkali metals, group 2 the alkaline earth metals, groups 3–12 the transition metals, group 17 the halogens and group 18 the noble gases. The older IA/IIA/IIIB style is also accepted when typing. Lanthanides and actinides other than La and Ac have no group number, so they are left out of the group questions.
- Is my progress saved?
- Your per-element statistics, best timed scores and best streak are saved in your browser's local storage, so they persist when you come back on the same device. Nothing is uploaded. Use “Clear history” above the heat map to start fresh.
