Question

Enthalpy electron gain enthalpy and electron affinity formula

Answer 1

Electron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom. Electron affinity is the same thing but only -ve sign is given before writting the value of electron gain enthalpy..

Answer 2

Answer:

if Ionisation Energy & Electron Affinity(Electron Gain Enthalpy) are in KJ/mol

Electronegativity = (Ionisation Energy + Electron Affinity)/5.6

if Ionisation Energy & Electron Affinity(Electron Gain Enthalpy) are in Electron Volts(eV)

Mullikan's values = 2.8 * pauling values.
