1. Electromagnetic radiation travels as _________
Warm Up- Write the sentence and fill in the blank! Ground, waves, absorb, decreases, short, increases
Electromagnetic radiation travels as _________
Electrons in the lowest energy level are at ______ state.
High energy electromagnetic radiation is associated with _______ wavelengths.
As wavelength increases, frequency ________.
As an atom is heated, electrons ______ energy.

2. How did you do? Electromagnetic radiation travels as _ waves _
Electrons in the lowest energy level are at ___ground___ state.
High energy electromagnetic radiation is associated with _short______ wavelengths.
As wavelength increases, frequency __decreases______.
As an atom is heated, electrons _absorb_____ energy.

3. Work on your Wave WS
You have 20 minutes to review your notes and complete the WS.

4. Atomic Orbitals
and
their shapes!!!

5. s Orbitals- spherical Each one can hold 2 electrons!
1s orbital s orbital

8. p Orbitals- the dumbbells
Each p subshell actually consists of three p orbitals of equal energy: px py pz
Each of the three p orbitals is dumbbell shaped and all are oriented perpendicular to one another.
The max. capacity of each p orbital is 2e-.
This accounts for the total capacity of the p subshell as being 6 e-’s.

9. Each p subshell consists of a set of three p orbitals of equal energy, px py pz

10. Shown together the three orbitals look like this

11. d Orbitals
The d subshell actually consists of a set of five d orbitals of equal energy
Each d orbital can hold a maximum of 2e- This accounts for the total capacity of the d subshell as being 10 e-’s
