Options

A. absrobs 2.0 e v kinetic energy
B. abosrbs 2.0 v potential energy
C. emits 2.0 eV electrical energy
D. emits 2.0 eV photon

Answer

To solve the problem of an electron jumping from a 7.00 eV energy level to a 5.0 eV energy level, we can follow these steps:

### Step 1: Identify the energy levels
The electron is transitioning from a higher energy level (7.00 eV) to a lower energy level (5.0 eV).

### Step 2: Calculate the energy difference
To find the energy difference between the two levels, we subtract the lower energy level from the higher energy level:
\[ \text{Energy difference} = E_{\text{initial}} - E_{\text{final}} = 7.00 \, \text{eV} - 5.00 \, \text{eV} = 2.00 \, \text{eV} \]

### Step 3: Determine the nature of the transition
Since the electron is moving from a higher energy level to a lower energy level, it is losing energy. This energy is emitted in the form of a photon.

### Step 4: Conclusion
The electron emits 2.00 eV of energy as it transitions from the 7.00 eV level to the 5.0 eV level.

### Final Answer
The electron emits 2.00 eV of energy in the form of a photon.
