The correct response is: Helium atoms have 2 valence electrons, while atoms of the other elements in the group all have 8 valence electrons.

Helium is unique among the noble gases (group 18) because it has only 2 electrons, filling its first energy level, while other noble gases like neon, argon, and xenon have 8 valence electrons in their outermost shell.
