To determine which element will have the greatest negative electron gain enthalpy from the given options, we need to analyze the electron configurations and the tendency of each element to gain an electron. ### Step-by-Step Solution: 1. **Understand Electron Gain Enthalpy**: - Electron gain enthalpy is defined as the energy change when an electron is added to a neutral atom in the gas phase. It is usually negative because energy is released when an electron is added. 2. **Identify the Given Elements**: ...
