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) + eā ā Xā(g) + energy Note that 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 differ by a negative sign. In solid state physics, the electron affinity for a surface is defined somewhat differently (see below). (Wikipedia).
Electron Affinity Trend, Basic Introduction, Chemistry
This chemistry video tutorial provides a basic introduction into electron affinity. it discusses the general trend of electron affinity as well as its many exceptions. Electron affinity is the energy change that occurs when a gaseous atom receives an electron. This video discusses which

In an ionic bond, two ions are held together by electrostatic force. These two atoms are trying to attain full valence shells of eight electrons. One atom has too many electrons and another has too few so one atom donates electrons and the other accepts them. The donor atom forms a cation,
