I (iodine)

Generally electron affinity increases from left to right across a period. Thus P (to the left of S in the same period) has a lower electron affinity thens S

And electron affinity decreases as you go down a group. Thus Se (below S in the same group) has a lower electron affinity then S.

Iodine, is in group 7A (or 17) which is to the right of group 6A (or 16), where sulfur lives). It has a higher electron affinity then S.

Google electron affinity for tables showing what an elements actualy affinity is.

Answer;

Iodine (I)

Explanation;

The reactivity of elements increases with an increase in the electron affinity. Reactivity of non-metals relates well with the concept of electron affinity. The greater the tendency of attracting electrons the more reactive an element is.
The electron affinity increases from left to right across a period and decreases down the groups of periodic table. This means phosphorus (P) and selenium (Se) have a lower electron affinity than sulfur, while Iodine has a higher electron affinity than sulfur and will thus greatly attract electrons from sulfur.
