The Periodic Table Challenge
Instructions:
- 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 or using the mouse. The table is not case-sensitive.
- Your results are automatically graded as you enter them. If "Enable auto-hints" is checked, the table will give you a hint after 3 consecutive bad guesses on an element.
- The exercise is over and the timer stops when you score 112. Challenge your colleagues to complete the table in the shortest time or with the fewest errors. For a fair competition, go by the shortest time and add a predefined time penalty for each incorrect attempt.
- To reset the table and your scores, simply reload this page.
- No clue? Cheat and take a look at a periodic table.
If you are curious, I'll tell you how this works as well as some of the history.
