What are Group 18 elements called?

Answer and explanation

Correct answer: Noble gases

The elements in Group 18 are called noble gases. This group includes helium, neon, argon, and other elements whose outermost electron shell is complete, giving them very low chemical reactivity under ordinary conditions. Halogens belong to Group 17, alkali metals are in Group 1, and transition metals occupy the central d-block. Hence, option A correctly identifies Group 18 elements.
