The negative electron gain enthalpy of fluorine is less than that of chlorine.

Text Solution

AI Generated Solution

To understand why the negative electron gain enthalpy of fluorine is less than that of chlorine, we need to analyze the factors affecting electron gain enthalpy in these two halogens. ### 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 atom in the gaseous state. A more negative value indicates a greater tendency to gain an electron. 2. **Atomic Size**: ...
