Periodic Table

Match all 118 elements with event names

The Periodic Table challenge matches parkrun event names to all 118 chemical element symbols. One event can fill more than one symbol, and you can complete more than one table.

Opens the challenge tracker on Periodic Table.

0/118 elements 0%
  • There are 118 elements to complete
  • For a normal 2-letter element symbol, the first letter of the symbol must match the first letter of the event name
  • The second letter of the symbol can appear anywhere else later in the event name
  • Example: Bushy Park can match B, Ba, Bh, Bk and Br
  • Xe (Xenon) is the special exception because there are currently no locations starting with X
  • For Xe, an event containing an x and then an e later in the name is acceptable, for example Bexley
  • Letters outside the standard UK alphabet, including accented letters, should not count as matches
  • Example: Zalew Wrzesiński would not match Zn, but it would match Zr
