4. I Can…
Correctly write the electron configuration for the first 56 elements in the periodic table

5. Location of an electron - probability in the electron cloud
Review
Location of an electron - probability in the electron cloud

6. Principle Energy Levels/Shell
n = principle energy level (P.E.L.)
The highest P.E.L. = the period the element is in
The further away from the nucleus, the higher the energy

7. Which would have a higher energy level, 3s or 4s? Why?
Check-In
Which would have a higher energy level, 3s or 4s? Why?
4s since it is further away from the nucleus

8. Orbitals s (1) p (3) d (5) f (7)
S = sharp
P = principal
D = diffuse
F = fundamental
s, p, d, and f indicate the shape of the orbital

9. Sublevels
A set of orbitals have equivalent energy

10. 2 electrons in each orbital
p = 6
d = 10
f = 14

11. Mark our Periodic Tables!!!!
Your choice:
Put info on the periodic table you have
Take a new periodic table
