About this quiz
A blitz edition of the first 20 elements. With three seconds a name there is no time to recite the table: type what comes to mind and fill the gaps afterwards.
- The full name is needed, not the symbol.
- The 20 names add up to 143 letters, so the round needs more than two keystrokes a second.
- Aluminum and sulphur are accepted.
