Safety Emporium for all your lab and safety needs
The Periodic Table Challenge
Challenging Classic Version 2.2b.4
NEW!: You can also try the Easier Instant Version of this resource which scores each element as you type it and offers easier hints.
- Click on a box and type in the 1 or 2 letter symbol for the element. You can move to the next box by hitting the TAB key.
- Submit your answers by clicking the Submit button above the table (or clear the entire table by clicking Reset). The table is not case-sensitive.
- Novice mode will show you which answers you got right and wrong. To make the table more of a challenge, normally all you get are the number that are right and wrong!
- No clue? Cheat and take a look at a periodic table.
If you are curious, I'll tell you how this works.
