WebElectron affinity The energy released when an electron is added to a neutral gaseous atom is known as electron affinity. The unit for electron affinity is kilo joules per mole. It depends mainly on two factors. They are atomic size and nuclear charge. Webopposite of electron affinity. There is an ionization energy measured for every electron in an atom. The first ionization energy is the amount of energy required to remove the first electron. The second ionization energy is the amount required to remove the second, and so on. A factor that affects ionization energy is electron shielding.

The electron affinity (Eea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion. X(g) + e → X (g) + energy This is not the same as the enthalpy change of electron capture ionization, which is defined as negative when energy is released. In other words, the enthalpy change and the electron affinity … Electron affinity is defined as The electron affinity is the potential energy change of the atom when an electron is added to a neutral gaseous atomto form a negative ion. So the more negative the electron affinity the more favourable the electron addition process is.
