Problem

Which atom in each set has the most exothermic electron affinity?

i) N, O, Ne

ii) Al, Si, Cl

a. i) Ne ii) Cl

b. i) N ii) Cl

c. i) O ii) Cl

d. i) Ne ii) Si

e. i) O ii) Al

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.
