FREE Expert Solution

We’re being asked to determine the element with the highest (most exothermic/ most negative) electron affinity


Recall that electron affinity is the energy change from the addition of 1 e to a gaseous element/ion


It is represented by this chemical equation:

Atom(g) + e  Ion(g), ΔE = –E.A.
