The element that is able to gain electrons and form an ionic bond is Iodine.
The term ionic bond has to do with the kind of bond that is formed between a metal and a non metal. In this type of bond, there is a transfer of electrons from the metal to the non metal. s such the metal would become positively charged while the non metal would become negatively charged as we can see in the crystal of the ionic compound.
We just have to look at the string of elements that we have been given because, this is how we can be able to make a decision about which of the elements would be able to gain an electron. While doing this, we must keep in kind that it is only the non metal that are able to gain electron within the context of forming an ionic bond.
