Question
**Energy Levels of an Electron in an Atom**

This energy diagram illustrates the allowed energy levels for an electron within a specific atom. The unit of energy is given as zeptojoules (zJ), where the SI prefix 'zepto' denotes \(10^{-21}\).

**Diagram Explanation:**

The vertical axis of the graph represents energy in zJ (zeptojoules), ranging from 0 to 1400 zJ. The horizontal axis is unlabeled, intended for visual organization.

- **Energy Levels:**
  - **A (Ground State):** The lowest energy level, around 200 zJ.
  - **B (First Excited State):** The middle energy level, around 400 zJ.
  - **C:** The highest energy level shown, around 800 zJ.

A red arrow indicates a transition from level A (ground state) to level C.

**Instructions to Complete the Table:**

1. **What is the energy of the electron in the ground state?**  
   Answer in [ ] zJ.

2. **What is the energy of the electron in the first excited state?**  
   Answer in [ ] zJ.

3. **If the electron makes the transition shown by the red arrow, from A to C, will a photon be absorbed or emitted?**  
   Choose either "absorbed" or "emitted."

4. **Calculate the wavelength of the photon that would be absorbed or emitted. Round your answer to 3 significant digits.**  
   Answer in [ ] nm. 

Note: You may need additional data or formulas to calculate the wavelength, such as the energy difference and the relation \(E = \frac{hc}{\lambda}\), where \(h\) is Planck’s constant and \(c\) is the speed of light.
