How do you find an electron affinity?

Explanation:

Electron affinity is the measure of an atom 's tendency to form a negative ion. Electron affinity can be measured by the amount of energy released when an electron is added to an atom to form a negative ion. When forming a negative ion, an atom undergoes the following reaction:: atom + electron (e -) -> negative ion + energy
