Problem: Which reaction below represents the electron affinity of Be?a. Be(g) → Be+(g) + e-b. Be(g) + e- → Be-(g) c. Be+(g) → Be(g) + e-d. Be(g) + e- → Be+(g)e. Be+(g) + e- → Be(g)

FREE Expert Solution

We’re being asked to determine the equation representing the electron affinity of Be


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.
