Answer:
A. Sulfur (S)
C. Nitrogen (N)
D. Chlorine (Cl).
Explanation:
The trend to gain electrons to form anions is found in the nonmetal elements.
From the group of the answer choices, you can see that the nonmetals would be sulfur (S), nitrogen (N), and chlorine (Cl).
Some examples of anions are N³⁻, Cl⁻, and S²⁻, so the answer would be A. Sulfur (S), C. Nitrogen (N), and D. Chlorine (Cl).
