4 cards from this section. Quick, good the night before a test.
What is meant by 'quantized energy levels'?
Think about the position of electrons in atoms.
Explain the relationship between photons and energy levels.
Consider how energy differences work.
What determines the energy of a photon?
Think about the relationship of energy to frequency.
True or False: Electrons can exist in any energy level within an atom.
Recall the definition of quantized energy levels.
If an electron transitions from an energy level of 3.0 eV to 1.0 eV, what frequency of photon is emitted? (Hint: Use E=hf)
Remember to convert eV to joules first!
How does the unique absorption spectrum of a substance indicate the elements present? Discuss the relationship between energy level transitions and observable spectra.
Think about why different elements have distinct energy levels.
