About this quiz
Every prompt is a small sieve over the first four periods of the table, hydrogen to krypton. No criterion is spare: drop any one of them and a second element fits.
- Twelve prompts lead to twelve different elements.
- Periods are the rows of the table and groups are its columns, numbered 1 to 18.
- An element that has been found leaves the board.
