Hey there!
Q- What is Electron Gain Enthalpy?
A- The amount of energy released while converting a neutral isolated gaseous atom to a negatively charged gaseous ion by the addition of electron is called electron gain enthalpy.
Electron Gain Enthalpy depends on two factors -:
1) Atomic Size -: The smaller the atomic size the greater is the electron affinity, because the effective attractive force between the nucleus and the valence electrons is greater in smaller atoms, and so the electrons are held firmly.
2) Nuclear Pull -: The greater the nuclear charge, greater is the electron affinity, because increase in nuclear charge increases the effective attractive force on the valence electrons.
