Answer:
Br - has the largest radius
Explanation:
These ions each have achieved the nearest noble gas configuration. Br - has a like electron configuration to that of Krypton, S2- has a like electron configuration to that of Argon, B3+ to Helium, Mg2+ to Neon, and Li+ to Helium.
_______________________________________________________
Traveling down a group, the radius tends to increase as atom gains another shell. Here we are comparing elements of like electron configuration to the noble gases Helium, Neon, Argon, Krypton. Krypton, being the last element present in the group out of the 4, has the greatest radius as it has the most shells. Thus, Br - has the largest radius.

Humans don't generally have a symbiotic relationship with earth. We take many of earth's natural resources and tear down the landscape of earth without putting any of it back.
