Question

Of the following elements, ________ has the most negative electron affinity.ISbSrTeSn

Answer 1

I has the most negative affinity, first option is correct.

Step-by-step explanation

Notice that electron affinity decreases down the group. When nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.
