Chemistry Nov. 3 & 4, 2015

•OBJECTIVE: Students will write electron configurations for several elements in order to show the arrangement of electrons.

•W.O. D. Sedate-to calm, soothe

•WARM-UP

1.What does the designation n=4 mean?

2.Name the sub-levels in n = 4?

3.How many electrons can n = 4 hold?

4.What is an atomic orbital?

HW

1.What does the quantum mechanical model determine about electrons in an atom?

2.How do sub-levels of the same principle energy level differ from each other?

3.The energies of electrons are said to be quantized. Explain what this means.

4.How many orbitals are in the following sub-levels: 3p, 2s, 4p, 3d, 4f?
