Which element, if combined with sulfur, will have the greatest attraction for the sulfur electrons? p se i

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.

It dont even matter because at the end of thre day we gone life like it ius s
