Electron Configuration Practice – Periodic Table Scavenger Hunt Each clue will lead you to the next element, either by giving you the atomic number or telling you to find the element in a specific period or group based on specific criteria. 1. Write out the electron configuration for Boron. How many electrons are in s orbitals? This value is the atomic # of your next element.

2. Using the element you just found, find an element in the same group that has its valence electrons in the n = 5 energy level. What is this element?

3. Write out the electron configuration for the element you just found. How many electrons total are found in the n = 1 and d orbitals of this element? This value is the atomic # of your next element.

4. Using the element you just found, find an element in the same period with 5 valence electrons. What is this element?

5. Write out the electron configuration for the element you just found. How many unpaired electrons does this element have? This value is the atomic # of your next element.

6. Using the element you just found, find an element whose atomic mass is about ten times the atomic mass of your current element. What is this element?

7. Write out the electron configuration for the element you just found. How many electrons are in the n = 3 energy level? This value is the atomic # of your next element.

8. Using the element you just found, find an element in the same group that is used in fluorescent lights. What is this element?

9. Using the element you just found, find an element that has the same number of electrons as double the atomic mass of your current element.

10. Using the element you just found, find an element in the same period that is a Noble Gas.

11. Using the element you just found, find an element in the same group that is used in party balloons.

12. Using the element you just found, find the element that has the same atomic mass as 24.5 times the atomic mass of your current element.

13. Write out the electron configuration for the element that you just found. How many electrons total are in the d orbitals of this element? This value is the atomic # of your next element.

14. Using the element you just found, find the element in the same row that has 7 valence electrons.

15. Write out the electron configuration for the element that you just found. How many electrons total are in the n = 2 and n = 3 energy levels? Take this total, add 1, and this value is the atomic # of your next element.

16. Using the element you just found, find the element that has the same number of valence electrons but in the n = 2 energy level.

17. Using the element you just found, if you make an anion with a -2 charge on this element, how many protons, neutrons, and electrons are in this ion? Add up the total number of subatomic particles. This value is the atomic # of your next element.

18. Write out the electron configuration for the element that you just found. How many unpaired electrons are in this element? This value is the atomic # of your next element.

19. Using the element you just found, find the element in the same period that has four valence electrons. What is this element?
