Which out of the `N` or `O` has higher electron gain enthalpy?

Explanation

To determine which element, nitrogen (N) or oxygen (O), has a higher electron gain enthalpy, we can follow these steps:

### Step-by-Step Solution:

1. **Definition of Electron Gain Enthalpy**:
- Electron gain enthalpy is the amount of energy released when an electron is added to a neutral gaseous atom. A more negative value indicates a greater tendency to gain an electron.

2. **Identify the Atomic Numbers**:
...
