Inside the official periodic table challenge
A child can take the official periodic table challenge right now in the Kids World Records quiz section. The quiz asks participants to identify the atomic numbers of the 118 elements, and the whole thing happens on screen — no experiments, no spoken answers.

This is a standardized identification record, so the attempt has to be completed through the Kids World Records quiz section. Attempts submitted outside that section will be rejected. Before a child starts, a parent or guardian should read the current Kids World Records FAQ, because that page holds the live rules for quiz-based records. Individual attempts are organised into age divisions of 4–6, 7–9, 10–12 and 13–16, and taking the quiz does not by itself guarantee a record.
What the Periodic Table Challenge actually tests
The official challenge is about one thing: identifying atomic numbers across the 118 elements. The modern periodic table runs from atomic number 1 up to element 118, so the challenge covers the full table rather than a short practice set.
While a child plays, the quiz screen shows two separate counters — one for correct answers and one for wrong answers — both visible as the attempt goes along.
It also helps to know what the challenge is not. It is not an open-ended general-knowledge test, where two children could get completely different questions at completely different difficulty levels. It is not a maths task, because nothing is being calculated. It is not a spoken activity, so there is no reciting, reading aloud or saying numbers out loud for a judge to interpret. The child answers on screen, and the quiz keeps the count.
Why the official quiz is the record route
Practising the table at home is fine. The attempt itself is a different thing: it only counts when it is completed inside the Kids World Records quiz section.
The reason comes down to fair comparison. Unofficial versions ask different questions, run on different time limits and score answers in their own way, so a result from one cannot be lined up against a result from another. The official quiz gives every child the same format, which is what makes one child's number of correct identifications comparable with another's. Custom question sets, printed lists, verbal versions and manually submitted substitutes are not accepted routes for this record.
Check the child's division first
Kids World Records sorts individual attempts into age groups so children are compared with others at a similar stage:
- Ages 4–6
- Ages 7–9
- Ages 10–12
- Ages 13–16
There are also boy, girl and gender X divisions. Confirm which ones apply before the attempt, because that is where the result would sit. Kids World Records does not run records based on being the youngest to do something — a seven-year-old takes part in the 7–9 age division rather than being set against teenagers.
An adult manages participation at Kids World Records, so a parent or guardian should be there from the first click rather than arriving afterwards. For families attempting anything for the first time, the general guide to breaking a Kids World Record is useful background reading.
One clear measurement
A Kids World Records title rests on one independent measurement. For this challenge, that means a single count of correct identifications under one official mode. It is never speed combined with accuracy, and never a mixture of elapsed time and number correct.
The official quiz page includes a control for switching quiz type, so what appears on screen can vary. Look at the live challenge before starting and see which mode it is offering. Kids World Records sets the approved formats; families do not set their own timing or invent a variation of their own.
The finer scoring logic is not spelled out in the page text either. How wrong answers, skipped questions or tied results are treated is not something to assume in advance — the mode shown in the live quiz, and the rules attached to it, govern the attempt.
Results, evidence and the scoreboard
Evidence is the part most families want settled before they start, and the straightforward answer is that the current Kids World Records requirements are the ones to follow. The FAQ sets out what is needed for applicable knowledge-based attempts, and it is the controlling reference for the on-site quiz as well. Playing the quiz should not be assumed to take care of every part of the process on its own.
Two practical points are worth knowing in advance. Kids World Records generally requires an attempt to be submitted within one year, so an older attempt should not be sent in. And the Quiz Score Board shows the current Periodic Table Challenge categories and standings. Those standings move, sometimes quickly, so look at them on the day rather than relying on a number you saw weeks earlier.
Ready to begin?
Sit down with a parent or guardian and open the official Kids World Records Periodic Table Challenge. Confirm the child's age and gender division, check which mode the live quiz is running, read the current requirements in the Kids World Records FAQ, and then play the whole attempt inside the official quiz section.
Learn the table as thoroughly as you like beforehand. When it counts, make it the official one.
