Warm-up: In the flame test lab, you "excited"
atoms in 2 ways. What is meant when we say an
atom is in an excited state? When is light emitted
from those atoms? What causes Lithium to give
off a magenta colored flame? Nowhere on the EM
spectrum is magenta.


Objectives: Understand the relationship between
wavvelength, frequency & energy of EM waves

Announcements: The flame test lab and
the Bohr model assignment should both be in your journal now.
