Step 1
: Understand the problem

To solve this problem, we need to understand that anions are negatively charged ions formed when an atom gains one or more electrons. Some elements are more likely to form anions because they have fewer electrons than stable noble gas configurations. These elements are usually found in groups 1, 2, and 16 - 17 of the periodic table.

Step 2
: Identify the elements that are more likely to form anions

Looking at the given options, we can identify the elements that are more likely to form anions: C. Sulfur (S) is in group 16, which only needs 2 more electrons to achieve a stable noble gas configuration (like argon, Ar). D. Fluorine (F) is in group 17, which only needs 1 more electron to achieve a stable noble gas configuration (like neon, Ne). So, the most likely elements to form anions are: - Sulfur (S) - Fluorine (F)

Final Answer

The elements most likely to form anions are Sulfur (S) and Fluorine (F).
