Consider the halogen family from fluorine to iodine which element would have the largest ionic radius?

Explanation:

Elements that belong to group 7A are known as halogen family members. The elements which belong to this group are fluorine, chlorine, bromine, and iodine.

It is known that when we move down a group then there occurs an increase in the size of atoms. This is because number of shells increases on moving down the group.

Since, fluorine is the top most element of group 7A so, it has the smallest ionic radius. Whereas iodine is thelargest in size hence, it has the largest ionic radius.

Thus, we can conclude that iodine is the element that would have the largest ionic radius.
