Question

Transcribed Image Text: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.
| Question | Answer |
|-------------------------------------------------------------------------|--------|
| 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 |
