Reviewing the Periodic Table Using Mystery Puzzles

This five puzzle mystery aligns with my chemistry curriculum after instruction on the properties of elements and electron configurations. I use this mystery as a review to prepare for assessments over the properties of elements, symbols on the periodic table and the difference between groups and periods. Also incorporated within the puzzles are basic trends such as the number of subatomic particles, mass number, melting point, and other characteristics of specific elements.
