What state are atoms most stable?
Gound state

Which orbital is the first to be filled in any atom? Why?
s orbital because you always fill lowest energy level first

As energy increases what happens to wavelength and frequency?
wavelength shortens and frequency increases

What is a line emission spectrum and how is it observed?
Distinct lines of color that come from excited atoms, often viewed with a spectroscope.
400
What does the Pauli Exclusion Principle tell us?
That each orbital contains only 2 electrons
