**Step-by-Step Text Solution:** 1. **Definition of Electron Gain Enthalpy**: Electron gain enthalpy is defined as the amount of energy released or absorbed when an electron is added to an isolated gaseous atom. 2. **Understanding the Process**: When an electron is added to a neutral atom, it can either release energy (exothermic process) or require energy (endothermic process). The energy change associated with this process is what we refer to as electron gain enthalpy. ...
