Normally no two elements have the same value of electron gain enthalpy. But there are two inert gases which have the same value of electron gain enthalpy. Name them.

Explanation

To answer the question regarding which two inert gases have the same value of electron gain enthalpy, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electron Gain Enthalpy**:
- Electron gain enthalpy is defined as the energy change that occurs when an electron is added to a neutral atom in the gas phase. It is usually expressed in kilojoules per mole (kJ/mol).
- For most elements, this value is unique, but there are exceptions.
