Electron affinity is the energy change that occurs as an atom gains electrons. Trends of the electron affinity include the following: Electron affinity increases across the periodic table from left to right due to nuclear charge increases. It also increases from bottom to top in the periodic table due to atomic size.

Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.
