Skip.
Question 4
Electrons reside in specific discrete energy levels.
True
False
Skip.
Question 5
Electrons can move from one energy level to another within an atom.
True
False
Skip.
Question 6
An electron needs exactly the amount of energy corresponding to the difference in energy levels in order to become excited.
True
False
Skip.
Question 7
The current model uses probabilities to determine where an electron is likely to be for a given energy state.
True
False
Skip.
Question 8
When electrons are excited to a higher energy level:
They will stay there indefinitely.
They will eventually fall back down to the lower energy level.
They can't be excited.
All of the above.
None of the above.
Skip.
Question 9
The solar system model:

Is consistent with all observations.
Correctly models the energy levels for hydrogen.
All of the above.
None of the above.
Skip.

All of the above.
None of the above.
Skip.
Question 11
Energy is inversely proportional to wavelength (as the wavelength goes up the energy goes down) and directly proportional to frequency (as the frequency goes up the energy also goes up).

Skip.
Question 16
The selective absorption of light by atoms and molecules gives rise to much of the color around us.
True
False
Skip.
Question 17
