Electron affinity
Electron affinity is a phrase used in chemistry. When an atom that is neutral gets an electron, the energy that is changed in the atom is the electron affinity. Across a period, the electron affinity increases. [1]

Electron affinity (Eea) vs atomic number (Z). Note the sign convention explanation in the previous section.
