Electron Affinity is the energy released from the addition of an electron to a gaseous atom or ion.

Periodic Trend: Electron Affinity (Simplified) Concept 2
Generally, electron affinity increases moving from left to right across a period and going up a group.
Periodic Trend: Electron Affinity (Simplified) Example 1
Determine which atom in the following set has the largest electron affinity:N, O, C, B, Ne
a) N b) O c) C d) B e) Ne
Rank the following elements in order of increasing electron affinity:Cs, Hg, F, S
Which one of the following atoms has the least tendency to gain another electron?
