34Se
22Ti
40Zr

5. Period # = Outer Energy Level
Includes lanthanides
Includes actinides

6. Elements in the Same Group
Elements in the same group have similar properties because they have similar electron configurations.

7. Sublevel Blocks of the Periodic Table

8. Not all periodic tables look exactly the same.

9. Not all periodic tables look exactly the same.

12. Periodic Table and Electron Configuration
s = period #
p = period # 1 2 3 4 5 6 7 1 2 3 4 5 6 7
d = (period# - 1) 6 7 6 7
f = (period# - 2)

13. Predict the electron configuration for the last sublevel.
