Erase the Periodic Table!


As the name of the competition suggests, you are to erase the periodic table by choosing the correct chemical symbol that pertains to the given element that will be shown. This is a test of knowledge and memory, which helps enhance officers and cadets alike in their memory recollection. Remember, if you click on one wrong answer or symbol, you are out of the game! Play here!


  • Participants can redo it as many times as they want but should only submit one entry.
  • Do not change the timer or the settings. You are only given 12 minutes to complete the table.
  • Submissions must include a screenshot of the completed table, including the time taken to complete it. If not completed, submit a screenshot of the answered portions. Ties will be broken based on the order of submission.
