Noble gases are used in many situations where a safe and constant environment must be maintained. For example, helium is used to provide a protective atmosphere for making fiber optics and semiconductors. Argon is used to fill incandescent and fluorescent light bulbs to prevent oxygen from corroding the hot filament. Why are noble gases used in these situations? A Nobel gases do not have a complete valence electron shell making them unstable and reactive. B Nobel gases have a complete valence electron shell making them unstable and reactive. C Noble gases do not have a complete valence electron shell making them stable and nonreactive. D Noble gases have a complete valence electron shell making them stable and nonreactive.
