Question
How does electronegativity differ from electron gain enthalpy?
Advertisements
Solution 1
Electron gain enthalpy is the enthalpy change that takes place when an electron is added to a neutral gaseous atom to form an anion. It can be negative or positive depending upon whether the electron is added or removed. An element has a constant value of the electron gain enthalpy that can be measured experimentally
Solution 2
Electron gain enthalpy is the tendency of an atom to attract outside electron. It is the property of an isolated atom.
