The feature that is unique to Group 18 nonmetals (the noble gases) is:
A. They are very nonreactive.
Noble gases, such as helium, neon, argon, krypton, xenon, and radon, are known for their lack of reactivity due to having a full outer electron shell, which makes them stable and unlikely to form compounds under normal conditions.
