Final answer:
The noble gases belong to the group of elements called nonmetals. These gases are known for their low reactivity and stable electron configurations.
Step-by-step explanation:
The noble gases belong to the group of elements called nonmetals. Nonmetals are elements that do not conduct electricity and have a variety of physical states. The noble gases, including helium, neon, argon, krypton, xenon, and radon, are found in group 18 of the periodic table. These gases are known for their low reactivity and stable electron configurations, which make them nonreactive.
