The electron gain enthalpy with negative sign for oxygen `(− 141 KJ mol^(−1))` is numerically less than that for sulphur `(− 200 KJ mol^(−1))`. Give reason.

Explanation

To understand why the electron gain enthalpy of oxygen is less negative than that of sulfur, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Definition of Electron Gain Enthalpy**:
- Electron gain enthalpy refers to the amount of energy released when an electron is added to a neutral atom in the gas phase. It is typically expressed in kilojoules per mole (KJ/mol) and is given a negative sign because energy is released during the process.

2. **Comparison of Oxygen and Sulfur**:
...
