Question

Consider a pretend atom for which the electrons can be in any one of the following energy states:

Start by arranging the four levels on a graph, then answer the following questions.
An electron jumps from one energy state to another, as described in each of the statements below. Describe whether a photon is absorbed or emitted in the process.
Absorbed: From level C to level B
Absorbed: From level D to level A
Emitted: From level A to level C
Emitted: From level C to level D

What is the energy of the photon absorbed in the transition from level D to level B? 9.000×10-19 J

Label each of the following photons as ones that can or cannot be absorbed by this atom without ionizing the atom. The value stated is the energy of the photon.
Can be absorbed Cannot be absorbed  7.00×10-19J
Can be absorbed Cannot be absorbed  2.00×10-19J
Can be absorbed Cannot be absorbed  1.30×10-18J
Can be absorbed Cannot be absorbed  9.00×10-19J
Can be absorbed Cannot be absorbed  4.00×10-19J

Explanation / Answer

If a photon with an energy equal to the energy difference between two levels is incident on an atom, the photon can be absorbed. So:

ANSWER: The only photon that CAN BE ABSORBED IS 2x10-19J

I hope it helps!!
