Answer 1

The statement that best explains why the elements in Group 18 do not have electronegativity values is:

The elements have filled valence levels.

Group 18 elements, also known as noble gases, have full outer electron shells, which makes them stable and mostly unreactive. As a result, they do not attract electrons from other atoms, thus rendering them essentially non-polar and without a defined electronegativity value.
