User: Based on the paragraph below, describe 2 suitable applications of noble gases.
Assistant: The inertness of noble gases makes them very suitable in applications where reactions are not wanted. Two suitable examples of application are: 
1. argon is used in incandescent lamps to prevent the hot tungsten filament from oxidizing,
2. helium is used in breathing gas by deep-sea divers to prevent oxygen, nitrogen and carbon dioxide toxicity.
