Which element with the following electronic configurations having maximum electron gain enthalpy.

Options

A. `1s^(2) 2s^(2) 2p^5`
B. `2s^(2) 2s^(2) 2p^(4) `
C. `1s^(2) 2s^(2)2p^3`
D. `1s^(2)2s^(2)2p^(6) 3s^(2)3p^(4)`

Explanation

To determine which element has the maximum electron gain enthalpy from the given electronic configurations, we will follow these steps:

### Step 1: Identify the Elements
We need to identify the elements corresponding to the provided electronic configurations.

1. **1s² 2s² 2p⁵**: This configuration corresponds to **Fluorine (F)**, which has 9 electrons.
2. **1s² 2s² 2p⁴**: This configuration corresponds to **Oxygen (O)**, which has 8 electrons.
3. **1s² 2s² 2p³**: This configuration corresponds to **Nitrogen (N)**, which has 7 electrons.
