Find out the application of all the inert gases prepare a chart and display it in the class
Answers
Inert gases are considered to be most stable and so they are un-reactive. They are used in many industrial purposes:-
• Helium – It is the lightest of inert gases and so it is used in hot air balloons like weather balloons, airships and other decorative balloons.
• Neon- It is widely used in advertising sign boards in the form of neon glow signs. It is also used for coating inner layer of tube lights.
• Argon – This is widely used in incandescent light bulbs and titanium production. It is also used for coating inner layer of bulbs.
• Krypton – It is widely used in semiconductor manufacturing and other circuit boards.
You can use this list to make the chat required here by simply putting two columns of:
a) Inert gas
b) Uses
i) Helium - due to its small density ( it is much lighter than air), it is used to fill air balloons and blimps.
ii) Radon - radon is used medically to destroy malignant growths. Radon emits gamma rays that are harmful to these malignant cells.
iii) Neon - when electric current is passed through neon gas under low pressure, it gives off a red glow. This is the reason why neon is used in advertising signs and glow lamps.
iv) Argon - argon is used in filament bulbs to protect the filament from burning as it prevents the oxidation of the metal used in making the filament.
v) Xenon - xenon is used in photography in flash bulbs because of its ability to emit instant intense light. It is also used in fluorescent bulbs and lasers.
