Solution Steps

Step 1: Placing electrons a, b, and c

According to Figure 3 (not provided), electron a starts at n=2, electron b starts at n=3, and electron c starts at n=5. On the provided energy diagram, place "a" on the n=2 energy level, "b" on the n=3 energy level, and "c" on the n=5 energy level.

Step 2: Drawing and labeling transition arrows

Model 1 in Figure 3 (not provided) shows electron 'a' transitioning from n=2 to n=1. Draw a downward arrow from n=2 to n=1 and label it 'a'.

Model 2 shows electron 'b' transitioning from n=3 to n=1. Draw a downward arrow from n=3 to n=1 and label it 'b'.

Model 3 shows electron 'c' transitioning from n=5 to n=4. Draw a downward arrow from n=5 to n=4 and label it 'c'.

Step 3: Determining absorption or emission

All the arrows drawn in the previous step are pointing downwards, which represents a decrease in energy level. A decrease in electron energy levels corresponds to the _emission_ of a photon.

Final Answer:

The electrons a, b, and c are placed on the energy levels n=2, n=3, and n=5, respectively. Downward arrows are drawn from n=2 to n=1 (a), n=3 to n=1 (b), and n=5 to n=4 (c). These downward transitions represent the emission of a photon.
