WARM-UP
1. Explain what each of the following means: (a) electrons are in the ground state.
2. Electrons are in the excited state.
HW
Prepare and organize your notes for a test on atomic structure (chapter 4 & 5) on Wednesday 11/30/16 (b day) and Thursday 12/1/16 (A day).
CW
In order to prepare for the test, complete the following in your note-books and bring your books to the teacher to receive credit for today.

2. Write electron configurations for each of the following elements, underline the valence level and give the number of valence electrons in each case: He, Li, B, N, F, Mg, S, Ar, Ca, Ni, Fe, Zn, Ge, & I
3. How are emission spectra produced?
4. Using fig. 5.12, explain hoe each of the following emissions are produced: (a) Lyman series (b) Balmer series (c) Paschen series
