What the correct answer 

### Electron Configuration of Vanadium (V)

The electron configuration for vanadium (V) is:

- \([Ar] \, 4s^2 \, 3d^3\)
- \([Ar] \, 4s^2 \, 4p^3\)
- \([Ar] \, 3d^5\)
- None of these

The correct answer is selected by a radio button labeled "None of these" highlighted in light yellow. This indicates that none of the provided configurations correctly describe the electron configuration for vanadium.

#### Explanation
- **Option 1: \([Ar] \, 4s^2 \, 3d^3\)**
  - This is the correct electron configuration for vanadium (V), but it is not selected in the given image.

- **Option 2: \([Ar] \, 4s^2 \, 4p^3\)**
  - This configuration is incorrect because the 4p orbital is not occupied before the 3d orbital in the periodic table sequence.

- **Option 3: \([Ar] \, 3d^5\)**
  - This configuration is incorrect as it does not include the 4s orbital.

- **Option 4: None of these**
  - This is the selected option in the image, which implies that the correct configuration is indeed not among the other options. However, this seems to be an error since the first option is correct for vanadium.

In conclusion, the correct electron configuration for vanadium is actually \([Ar] \, 4s^2 \, 3d^3\).

#### Practical Application
Understanding the electron configuration is crucial for comprehending the chemical properties and reactivity of the element. For instance, vanadium’s electron configuration allows it to form various oxidation states, which is important in applications like catalysts in chemical reactions.
