CHEMISTRY NOV.5 & 7, 2018

OBJECTIVE: Students will write electron configurations and draw orbital diagrams in order to describe the arrangement of electrons around the nucleus of an atom.

W.O.D. Enervated-lacking energy, weaken, exhausted

WARM-UP
Arrange the following atomic orbitals in increasing order: 3d, 2s, 4s, 1s, 3p

CW

Complete the following in your notebooks

1. Page 136 #9, page 137 #11-14

2. Draw orbital diagrams for each of the following atomic orbitals (a) 2s1 (b) 3p5 (c) 4d7 (d) 5f12 

3. How are atomic emission spectra created and used?
4. Explain what is meant by (a) electrons in the “ground state” (b) electrons in the “excited state”.
5. What are photons?
6. Describe the photoelectric effect.
7. Write the equation used to determine the energy of photons
