Periodic Table Unscramble

Periodic Table Unscramble is a challenge that debuted in Big Brother: Stranger Things.
== Rules ==
Houseguests are given a string of chemical elements on the periodic table. To get the correct answer, they must shorten the chemical element name to its chemical symbol. For example, "Helium Xenon" would be the word "hex". If there is a tie for the amount of prompts answered correctly, then the houseguest's time taken will be used as a tiebreaker.
Discussing the challenge with other players is forbidden, while googling to help you with the symbols is allowed.
== History ==
This challenge was first used as a Head of Household challenge in the Week 3, also known as Upside-Down Week, of Big Brother: Stranger Things. The top three were Webb, Dawn, and Shelby, with Webb ultimately winning the challenge. As part of the Upside-Down Week twist, Webb was awarded the sole vote to evict and used this to evict Yoohoo.
