In the following, the element with the highest ionization energy is

Options

A. `[Ne]3s^(2)3p^1`
B. `[Ne]3s^(2)3p^3`
C. `[Ne]3s^(2)3p^(2)`
D. `[Ar]3d^(10)4s^(2)4p^2`

Explanation

To determine which element has the highest ionization energy among the given options, we will analyze the electronic configurations of the elements in question and their stability.

### Step-by-Step Solution:

1. **Identify the Elements and Their Electronic Configurations:**
- **Option A**: Neon (Ne) - Configuration: \(1s^2 2s^2 2p^6\) (Noble gas, fully filled)
- **Option B**: Arsenic (As) - Configuration: \( [Ne] 3s^2 3p^3 \) (Half-filled p subshell)
- **Option C**: Silicon (Si) - Configuration: \( [Ne] 3s^2 3p^2 \) (Not half-filled or fully filled)
- **Option D**: Germanium (Ge) - Configuration: \( [Ar] 3d^{10} 4s^2 4p^2 \) (Not half-filled or fully filled)

2. **Analyze the Stability of Each Configuration:**
- **Neon (A)**: Being a noble gas, it has a fully filled outer shell, which makes it very stable. However, ionization energy is not exceptionally high compared to other configurations.
- **Arsenic (B)**: It has a half-filled p subshell (3p^3), which is exceptionally stable due to exchange energy and symmetry. This stability means it requires significantly more energy to remove an electron.
- **Silicon (C)**: With the configuration \(3s^2 3p^2\), it does not have a half-filled or fully filled subshell, so it can ionize more easily than arsenic.
- **Germanium (D)**: Similar to silicon, it has \(4s^2 4p^2\) and does not have a half-filled or fully filled subshell, making it less stable than arsenic.

3. **Compare Ionization Energies:**
- The element with a half-filled p subshell (Arsenic) is expected to have the highest ionization energy due to its extra stability.
- Neon, while stable, does not exhibit the same level of ionization energy as arsenic in this context.
- Silicon and Germanium have lower ionization energies due to their configurations.

4. **Conclusion:**
- Among the options, **Option B (Arsenic)** has the highest ionization energy due to its half-filled p subshell configuration, which provides extra stability.

### Final Answer:
The element with the highest ionization energy is **Option B (Arsenic)**.
