Please explain the difference between Electron Gain Enthalpy and Electron affinity.

6 years ago


Answers : (2)


Dear shivanshu,

The standard enthalpy change accompanying the attachment of an electron to an isolated atom (or ion) of the element in the gas phase

The electron gain enthalpy value is negative.

Electron affinity is the negative of electron gain enthalpy and hence electron affinity is a postive value.
