The correct response is:
Helium atoms have 2 electrons, while atoms of the other elements in the group all have 18 electrons.
This statement highlights the key difference in the number of electrons between helium and the other noble gases in group 18 of the periodic table. Helium has a full outer shell with 2 electrons, while other elements in this group, like neon, argon, and others, have a full outer shell with 8 electrons.
