###### FREE Expert Solution

We are asked to choose which among the given elements tend to form anions in binary ionic compounds.

Recall that a binary ionic compound involves the bond between a cation (positive ion) and an anion (negative ion).

The cation is a positive metal and the anion is a negative nonmetal. Let us look at each of the given choices and identify each type. Remember that we are looking for negative nonmetals.
