Question

which of the following best describes why noble gases do not form compounds? o they have large atomic numbers, giving their nucleus a strong positive charge. o they have low boiling points. o their full valence shell makes them unreactive. o they have not been discovered yet.

Explanation:

Noble gases have full valence shells. This stable electron - configuration makes them unreactive and less likely to form compounds.

Answer:

Their full valence shell makes them unreactive.
