I like students to be comfortable with the periodic as a tool for their use in chemistry, rather than a sheet of information that they memorize. To keep students up on using the periodic table as a tool, I periodically (no pun intended) ask them to search the periodic table through a scavenger hunt.
I have provided an example below.
Periodic Table Scavenger Hunt
Hint: Symbol
1. Start at the element that is a waste product of photosynthesis. __________ O
2. Add seven AMU’s to the mass __________ Na
3. Add 26 to atomic number __________ Rb
4. Remain in that period and go to Group IB __________ Ag
5. Go up one period and to the right six groups __________ Br
6. Go to the top of that family __________ F
7. Remain in that period and divide the electro-negativity by two __________ B
8. Add fifty to the atomic number __________ Cs
9. Go to the element that is a liquid at 25o C in that period __________ Hg
10. Increase the proton count by six __________ Rn
11. Go to element with the smallest mass in that group __________ He
12. Multiply the atomic number by ten __________ Ca
13. Decrease the proton number five __________ P
14. Jump to Group IIA in that period __________ Mg
15. Cut the atomic number in half __________ C
16. Decrease the mass by 3.0 AMU’s __________ Be
17. If the element is an even atomic number multiply by 4
If the element is an odd atomic number multiply by 5 __________ S
18. Jump up one period. You should be back where you began. __________ O
While this isn't some earth shattering method of exploring the periodic table, it does provide students with familiarity with the elements, information and terminology necessary to use the periodic table efficiently and effectively.
