Electron Gain Enthalpy
The enthalpy change accompanying the process of adding an electron to a neutral gaseous atom to convert it into a negative ion is known as electron gain enthalpy. This process is represented by the equation:
X(g) + e- → X-(g)
Explanation
- When an electron is added to a neutral gaseous atom, energy is either released or absorbed. If energy is released during this process, it is called exothermic electron gain enthalpy. If energy is absorbed, it is called endothermic electron gain enthalpy.
- The magnitude of electron gain enthalpy depends on various factors such as the size of the atom, the effective nuclear charge, and the electron configuration of the atom.
- Electron gain enthalpy is a measure of the ability of an atom to attract an additional electron. Elements with higher electron gain enthalpy values tend to form negative ions more readily.
- The electron gain enthalpy values of elements can be used to predict their chemical reactivity and their ability to form ions in chemical reactions.
- Electron gain enthalpy is an important concept in the study of chemical bonding and the formation of ionic compounds.
In conclusion, electron gain enthalpy is a crucial parameter in understanding the behavior of atoms and their tendency to gain electrons to form negative ions.
