Warm Up- Write the sentence and fill in the blank! Ground, waves, absorb, decreases, short, increases 1. Electromagnetic radiation travels as _________ 2. Electrons in the lowest energy level are at ______ state. 3. High energy electromagnetic radiation is associated with _______ wavelengths. 4. As wavelength increases, frequency ________. 5. As an atom is heated, electrons ______ energy.

3
How did you do? 1. Electromagnetic radiation travels as _ waves _ 2. Electrons in the lowest energy level are at ___ground___ state. 3. High energy electromagnetic radiation is associated with _short______ wavelengths. 4. As wavelength increases, frequency __decreases______. 5. As an atom is heated, electrons _absorb_____ energy.

4
Work on your Wave WS You have 20 minutes to review your notes and complete the WS.

5
Atomic Orbitals and their shapes!!!

6
s Orbitals- spherical Each one can hold 2 electrons! 1s orbital 2s orbital

p Orbitals- the dumbbells Each p subshell actually consists of three p orbitals of equal energy: p x p y p z 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.

10
Each p subshell consists of a set of three p orbitals of equal energy, p x p y p z

11
Shown together the three orbitals look like this

12
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
