Test your knowledge of the chemistry periodic table
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 109. 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.
