About this quiz

The chain is a walk across the main table, hydrogen to radon. Moves go one or two places along a row, up or down a column, or to the alkali metal, halogen or noble gas of a row.

  • Thirty steps visit thirty different elements; none is repeated.
  • A wrong pick shows the right element, so the chain can always go on.
  • The lanthanides are not in the chain, and no move passes through them.
