nobel gasses

Explanation:

Anions are negatively - charged ions. Non - metals gain electrons to form anions. Metals form cations (positively - charged ions). Halogens (a subgroup of non - metals) do form anions, but the more general group is non - metals. Noble gases are generally inert and do not easily form ions.

B. nonmetal
