Question
This energy diagram shows the allowed energy levels of an electron in a certain atom. (*Note:* the SI prefix 'zepto' means \(10^{-21}\). You can find the meaning of any SI prefix in the ALEKS Data tab.)

**Diagram Explanation:**

- **Graph:** The y-axis represents energy in zeptoJoules (zJ), ranging from 0 to 1400 zJ.
- **Energy Levels:** There are three horizontal lines labeled A, B, and C at different energy levels.
  - Level A is at approximately 200 zJ.
  - Level B is at approximately 600 zJ.
  - Level C is at approximately 1000 zJ.
- **Red Arrow:** Indicates a transition from level A to level C.

Use this diagram to complete the table below.

|-------------------------------------------------------------------------|--------|
| What is the energy of the electron in the ground state?                 | \_\_\_ zJ  |
| What is the energy of the electron in the first excited state?          | \_\_\_ zJ  |
| If the electron makes the transition shown by the red arrow, from A to C, will a photon be absorbed or emitted? | ☐ absorbed ☐ emitted |
| Calculate the wavelength of the photon that would be absorbed or emitted. Round your answer to 3 significant digits. | \_\_\_ nm |
